RIM shows PlayBook tablet, will not undercut iPad in price

post #1 of 89
Thread Starter 
BlackBerry maker Research In Motion has started showing its new PlayBook to developers, releasing more details about the new prototype device including the fact that it will not undercut the iPad in price as was recently rumored.

According to a report by ZDNet, RIM is in the process of meeting with core developers at events in Toronto, New York and San Francisco.

Hardware price and performance

Among the details gleaned in the report is that there will be three models, similar to the WiFi-only iPad, with 16, 32 and 64GB capacities. This contradicts the claims of Mobility Insider, which stated RIM would offer a $399 8GB version that could undercut the entry level iPad's price by $100.

The iPad undercutting price rumor was already suspect, given that RIM's own executives had only ever stated that they planned to price the PlayBook starting "under $500," which for a 7 inch screen tablet would only make it comparable to the more than twice as large iPad.

Apart from offering Apple little competition in terms of aggressive pricing, the PlayBook was said to look good up close, with a "very nice glass similar to the iPad. The build quality is better than current Android tablets on the market," the report noted.

The PlayBook reportedly uses a 1GHz dual core ARM Cortex A9 processor, which would suggest a year's leap of progress over last spring's iPad, which uses a 1GHz A4 with a single A8 CPU core. Observations of its speed range from comments that it "looked smooth overall" to Engadget's comment that "it looks pretty slick -- though there is some slight animation lag."



Operating system and apps

Performance issues could certainly be attributed to the fact that the PlayBook operating system isn't finished yet. There are also only a few prototypes available for developers to look at. The ZDNet report stated that in New York, there were around 150 developers but only three or four units available.

Worse for developers, RIM isn't offering a PlayBook emulator with a functional web browser yet; the PlayBook itself lacks a functional browser. "This item is no small issue since there are a lot of HTML5 developers in the house," the report noted. RIM's initial plan for PlayBook apps is to leverage web standards, so it plans to get a functional browser emulation environment to developers by early January when it finishes the PlayBook's browser, which based on Torch Mobile, a WebKit implementation that RIM acquired last fall.

Prior to that, the PlayBook can only run Adobe AIR apps created using Flash Builder. Theoretically, these apps should be portable between PlayBook and Android, which also supports an AIR runtime on some new models. However, developers report "AIR apps can be tough to port," and the report also noted that "BlackBerrys biggest developers are unlikely to use AIR. Those BlackBerry developers are likely to wait until January or February when the BlackBerry OS kit is available. In a nutshell, youll have AIR apps early and Java developers will hold back."

The current crop of around 50 apps are all built using AIR. Next year, RIM plans to launch a web-based development platform named WebWorks, similar to Palm's webOS or Google's Chrome OS. Additionally, it also plans to launch a native C/C++ software development kit "for non-Flash apps and Java," with support for "OpenGL 2.0, networking, data storage all native" the report said.

PlayBook & BlackBerry cross polination

It is not clear if RIM plans to bring existing BlackBerry app compatibility to the PlayBook (which would require hosting a Java VM, as the existing BlackBerry OS is Java), but this seems unlikely given the very different experience promised by the PlayBook's iPad-like, albeit smaller, screen compared to the trackball and microbutton keyboards that gave existing BlackBerry devices their name.

When pressed to suggest when the PlayBook's still unfinished new software platform would trickle down into the company's BlackBerry smartphones (something RIM has promised to do at some point in the future), the company's co-CEO Mike Lazaridis stated in an interview that would happen "as soon as I have dual core baseband CPUs" capable of running within smartphones.

However, just this spring Lazaridis claimed that touch-only phones like the iPhone arent that popular, and that most of the people buying touchscreen phones were subsequently going back to phones with hardware keyboards, like those that made RIM famous.

A lot of work, little time

The development efforts RIM has outlined for the next 30 days are nothing short of Herculean. Apple spent a full year working on the original iPhone SDK after its initial launch, despite its being largely based upon existing, tested Cocoa frameworks used in Mac OS X. Essential features such as copy and paste, multitasking, and system wide search were delayed for years to get the basics out first. Apple also spent years developing expertise in its mobile Safari web browser, following years of WebKit development.

Similarly, Microsoft delayed Windows Phone 7 for years longer than planned, and it was "only" refreshing Windows Mobile and building a mobile version of Silverlight, not building a whole new operating system environment from scratch. Microsoft has also long been the top PC web browser vendor, but struggled for years to deliver a reasonably functional mobile browser of its own.

Palm rapidly brought its new webOS to market after a year or two of work, but it was largely overlooked because it couldn't offer the maturity of existing platforms right out of the gate. Since HP's acquisition, Palm's operating system has only made minor progress over many months.

Even Google has delayed its Chrome OS for a year longer than planned, and that product is "just" a web browser hosted by a standard Linux kernel with nearly no exposed operating system services. Google is also indisputably an expert in web browser development.

RIM is essentially working to match the efforts of Palm, Google, Microsoft and Apple all at once, within a few months, while transitioning itself from its familiar territory as the vendor of mobile terminals tethered to an enterprise server infrastructure into an entirely new and unfamiliar mobile PC market, using an OS kernel it just acquired less than a year ago, a browser code base it bought last fall, and developing an entirely new platform it hasn't ever pulled off before as a basic JavaME licensee.

In October, Apple chief executive Steve Jobs dismissed RIM rather quickly in his remarks to analysts, noting that the iPhone 4 "handily beat RIM's 12.1 million Blackberries sold in their last quarter. We've now passed RIM. I don't see them catching up with us in the foreseeable future."

Jobs added, "it will be a challenge for them to create a mobile software platform and convince developers to support a third platform."

I'm thinking that maybe Palm is the real point of comparison for RIM going forward. They managed to get a well received and by all reports pleasant to use OS out the door, but broke compatibility with their installed user base. Thus, the lack of apps and the comparatively lackluster developer environment couldn't generate enough buzz and goodwill to break through new platform inertia.

MS, of course, has done something similar with WP7, but MS has a lot more going on (and many more revenue streams) than just a mobile operating system and can use that to help prop things up until if and when their new phone OS gets some critical mass.

So if RIM has to basically start over with a new OS, then they have to pretty much start over in the marketplace. Sure, there's some product loyalty and name recognition, but the fabled BB installed user base lock-in behemoth pretty much counts for nothing. An army of Palm users didn't do the Pre much good, we'll see if QNX phones can do any better.

The need to play the hardware-specs trump card is becoming antiquated. While I'm sure faster hardware can make badly-written software seem to run better, in the end it comes down to optimization and taking to time to polish and do everything that one can do to get everything running fluidly. Where mobile devices are concerned, Apple has proved to me that it is not important the Ghz speed, or how many cores a CPU has, only that engineers have taken the time to get the two aspects (hardware and software) to complement each other.

RIM at least has a better shot than the other players. Like Apple, they appear to be in control of both the hardware and software. The disadvantage they have (IMHO) is that their software support is lacking to say the least, and they certainly do not have the software engineering talent that is comparable to what Apple has. This is where I think RIM will fail.

It's difficult to try matching Apple's offerings at the same price points due to Apple's ability to control the economies-of-scale. They have so much clout in obtaining all the components at the best prices. It leaves everyone else picking up the breadcrumbs that are left over.

Wow... looks like RIM is really behind on this project. They don't really seem to have the ecosystem in place to make 1.0 viable, and it might take as long as 3.0 to really get it moving. (...if they have that long!)

I do hope Apple hurries up and makes my iPad obsolete with a newer version. Yes, I want higher resolution, faster processor, and a Gig of RAM. Camera would be nice as well... or at least a standard way to interact with cameras directly.

Given that they're starting with a proven OS I have no doubt they can get something out the door. It's an open question if that something actually performs well as a modern tablet OS, and whether or not it's so orthogonal to their existing business as to be pointless.

My guess is that latter point could be a pretty major hangup, and one that wouldn't be evident from demos. I could see the whole Playbook thing turning into RIM's Copland, the Big Leap Forward that becomes hopelessly entangled in compatibility issues and keeps getting pushed further and further out.

Although from the way they're talking, I get the feeling that they're just sort of winging it, at this point, and would probably release almost anything just to be doing it.

Economies of scale means that Apple can have a higher profit margin. RIM already has the second highest profit margin in the industry.

That's a major concern.
post #12 of 89
Not to jump on the bashing wagon here but how on earth will someone choose this over an iPad or iPad2?

Imagine if Apple keeps producing the 1st Gen (a-la iPhone 3G) and drops its price to 399-ish while introducing the iPad2 at the same price points we see now with the iPad?...

The fact that Apple will be releasing iPad2 so shortly (<12mths after iPad1) seems say they are really going for the jugular.
post #13 of 89
So it's slower, smaller, and has almost no apps, but it will be the same price as the iPad? Hmmm ...

That'll work!

This part I don't understand.

All the reports I have seen say that the entire UI is written using Adobe Air. The underlying OS is QNX, but the windowing system, the transitions, etc. are all written in Air last I heard. I could easily be wrong, but the description given here doesn't really make sense either. Please clarify it a bit.

Except RIM is not moving their smart phones to the new OS; it is just for the tablet, for now, apparently.

Completely agree on this point. Apple has proven that optimization can give and save you more in the end. OS X, at its core, is a highly tuned OS, built for multi-processing. And has added many features to allow developers to easily optimize their own applications. Spouting off CPU speeds and core counts is irrelevant if the system isn't making use of all the resources available to it.

And since Apple is designing their own SoCs, they can strip down and fine tune the hardware as well.

This is true and, as usual, will be overlooked by tech pundits even though the iPad 2 will probably be released before the PlayBook.

Right, but then what is it for? It's not a BB device, it's barely a RIM device at all, in the marketing sense. What's the value proposition, for the consumer, against the established incumbents?

And RIM is saying (I think, their CEO is exceptionally incoherent) that they plan on moving their phones to QNX as soon as the hardware will support it, so something's got to give, and it had better be sooner than later.

They chose the wrong screen size. The thing will be DOA. We know that already.

Everything else is frosting on the cake.

Another thing that came out is that parts aren't multi core optimised yet.

It sounds like they have brought all this cool stuff (from QNX, Torch Mobile) but haven't appreciated how long it will take to mold them into a shipping product.

How long is very subjective. They are trying to do it in months while historic exsamples have been in years.

I'm guessing they'll move their phones to the new system, if/when it catches on and establishes itself as a competitive platform. Although RIM is slipping, the Blackberry is still one of the larger smart phone platforms on the planet. They don't need to rush the phone just yet as long as they can work to build a new platform around a different device. The tablet market is a new to RIM, they're free to test the market without needing to disrupt their main revenue stream. This is true for Microsoft as well. If RIM were to switch their entire business cold-turkey, it could do more damage then good (i.e. Palm).

I guess we'll see if RIM fumbled this by announcing and showing a tablet too early. If they can't deliver, if they have to start announcing shipping delays, it's just going to add to the sense that RIM is a company mired in the past that can't execute in the new market.

That's not a given, maybe they waited until they were sure they had something solid before going public, but the weirdly muddled pronouncements of their management doesn't make me very optimistic on that count. I mean, you can sort of imagine the decision being made to buy QNX, the QNX engineers showing up before a largely uncomprehending RIM management going "Oh hell yes, we got this!" and RIM management rushing out to tell everyone about the super cool new tech that they've just been assured can get the job done, without really understanding much about it.

You really have to weed through all the insanely biased and somewhat childish commentary, but within most articles on this site AppleInsider really delivers an excellent nugget or two of great observations and analysis.

But even if they announce any delay --- it would still be in months instead of years (as in historic examples like the Copland or webos).

I was skeptical that the iPad screen is “more than twice” as large, but I did the math. By area, it is:

iPad: 1024x768
7.76” x 6.82”
45.2 square inches

PlayBook: 1024x600
3.54” x 6.04”
21.4 square inches

So when Steve Jobs said a 7” screen is like taking the iPad screen and cutting it in half, he was being generous. It’s not even as big as that.

The PlayBook also has a narrow format (like a 16:9 movie), which means the landscape keyboard would take up most of the screen, while the portrait keyboard would be extra small. Since these devices are for all kinds of general use, not movies above all else, I think the iPad’s less extreme shape makes good sense.

P.S. iPhone/iPod for comparison: 960x640
2.91” x 1.94”
5.65 square inches (about 1/4 of the PlayBook or 1/8 the iPad)

(Those inch dimensions come from the known diagonals and pixel sizes and our friend Pythagoras.)

I understand the advantages of a RTOS... what I don't understand is what user benefits it will bring to a smart phone or even today's tablets.

PlayBook is nothing more than a repackage of the QNX + Adobe Air embedded platform, originally intended for vertical applications in the automotive, industrial, medical and other industries --i.e. inside limited purpose devices.

QNX Automotive PDF

No wonder they can be showing all these demos so early. Definitely a forte of Flash.

But the big question remains whether the QNX embedded platform is suitable as a general purpose computing device.

With what we've seen in those demos, I don't think we have an answer. \

Well, we don't know that. We've seen demos of very limited functionality from a device that's not interacting at all with a larger ecosystem. From what I've seen, they could have gotten that far just by putting a tablet around one of the existing QNX embedded application environments.

So there's no real way to tell, at this point, what hurdles still RIM still faces in order to make this, not just a general purpose computing device, but one that has some relevancy to their existing business.

Isn't that a spec rather than a benefit?

Also, doesn't the smaller footprint result, to a large degree, from: a) the ARM architecture; b) unneeded hardware removed (drivers, HDD, OD); c) economies of SOC packaging (ala the A4); d) optimization and packaging of the OS for the target devices (ala iOS).

I am serious here -- A RTOS has advantages/benefits when monitoring/managing a lot of rapid realtime activity in an automobile, router, etc. But, what does that capability bring to an iPhone or a tablet?

Specifically, what can be done better, faster with a RTOS on the kinds of things a smart phone or a tablet can practically perform?

We are talking about resource constraint environment with limited RAM and CPU speed. A couple of megabytes saved here and there may not mean much on the desktop, but on a cell phone that may be a lot.

As I posted in another thread, the hurdles may not be entirely technical:

RIMs 3Q FY2011 earnings call is on the 16th of this month.

Their 4Q FY2011 closing is the end of Feb 2011.

I think that RIM needs to show some pretty good numbers!

I also believe that RIM needs to get a Technical SVP, who is well-spoken and can think on his feet -- to act as the single executive/spokesman for the PlayBook related activities. (Muzzle the co-CEOs, other than to introduce the SVP).


Lacking that, the PlayBook will surely fail, IMO.


If it fails, who will pick up the crown jewels (QNX, TAT, etc.) ?

I agree with saving a couple of megabytes of RAM and SSD!

But iOS and Android run with 256 MB RAM -- a lot less than the 1 GB RAM (minimum apparently required) on the PlayBook and future QNX-based BB replacement phones.

Where, exactly, is the smaller footprint of QNX RTOS? How much smaller than iOS? Than Android?

None and nothing. Because this assumption is based on the unproven premise that iOS contains things it does not need. It is not OS X, it is much lighter (e.g. lacks tons of drivers and interfaces). There is zero difference between a RTOS and an non-realtime OS on a tablet or phone, if the regular OS has been slimmed down to only support the functionality required on a device. There is also no general speed advantage (with e.g. processing messages) when comparing a process on a RTOS with one scheduled to run with the highest priority under a regular OS.

The only real benefit (a theoretical one and one that does not affect the user at all) is that RTOSs can switch off unneeded parts of themselves dynamically, e.g. you could deploy the very same version of an OS to different devices with different capabilities and the system could optimize itself for each of them. Apple has to do this the hard way by providing different downloads for different devices.

Thank you! I understand! Someone like Apple who makes an universal OS for a wide range of hardware would benefit from a RTOS that could scale itself to its environment (rather than being manually scaled and deployed).
