    What development tools are you talking about? The HDMI out simply mirrors whats on the screen. Developers don't need to do anything for that.

    You win. I concede defeat. I no longer want to attempt developing an app for the Playbook.



    They are ALL rushing to get the tablets launched. Apple has the luxury of dropping features from the initial launch to a later date.

    IOS 4.3 beta 1 didn't come out to developers until middle of January.



    You are mixing the 2 arguments up. I said that the 9x faster GPU has the power to decode 1080p --- but Apple's own codec team probably didn't have the time to code their decoder to take advantage of the new GPU hardware to give you 1080p decode.

    What features did Apple drop?

    The hardware has the capability to decode 1080P. But so far Apple has not implemented anything in the software that takes advantage of that capability. So for right now there is nothing specific for developers to do.



    Its likely that you are jumping the gun on all of this. And that Apple will introduce some new features with iOS 5.

    You think that the lack 1080p decoding is because Apple wants to put that feature in iOS 5 --- Apple also has the option of charging wifi ipad users for upgrading to iOS 5.

    Many will argue that this is not an issue because modern Garbage Collection schemes are quite efficient -- and can theoretically outperform manual memory management.



    I have no links/citations, but, I have read that there are periodic, noticeable performance hits with Android due to pauses/jitters related to Garbage Collection.



    If GC is poorly implemented on Android, one way to compensate is to throw hardware at the problem. (In mainframe parlance: "There is no substitute for Cubic Inches").



    So, it may be to support equivalent capability/performance an app on the iPad requires less RAM (and other hardware) than on Android.





    I also think the PlayBook approach to addressing Flash & UI issues is to throw hardware at the problem.





    IMO, this the exact opposite approach than should be used in the power/weight/battery constraints of a mobile device.



    .



    'Zactly!



    As for GC, if you are careful you can pretty much make it a non-issue. But is painful and not particularly good for programmer productivity to always be worried about GC and designing/implementing it away. Thus we usually see the naive Java application implementations with warts.

    I do not even know how many mmore text, images and all sorts of files I have now, a lot of them are also stored in the internet. I am now in my second external disk drive (more than 1 Terrabyte) on top of the internal drive. I don't even do systematic backup because it could easily increase the size by several fold.



    So, I am not sure if the issue of random storage still happens in the OSX.

    Stop right now and back up!!!



    Really. Stop. Back up.



    Your hard drives will stop working. That's what they do. There's no hard drives never stop working. You need data on at least two drives so that when one stops working the other drive will still have your data. Hard drives stop working somewhere between the time they are first turned on, and sometime after that.



    I think you confused rebuilding the desktop database with defragmenting a hard drive. Those are two different things. Rebuilding the desktop database was done in OS 9 and earlier and was a separate issue from disk fragmentation.



    Disk fragmentation still happens in OS X, but under normal use, it's not a consideration. OS X automatically defragments on the fly (re-allocating files that are 20MB or less). If there's enough free space on the drive (and it's HFS+), it won't fragment at all.



    Did I mention that you should back up your hard drives?



    Always buy your hard drives in pairs (at least). TimeMachine is wonderful, but so are tools like Carbon Copy Cloner.

    What software features did they drop, that there's actually some evidence that they did, not just your wild conspiracy theories?



    As usual, you're talking bullshit, samab.

    Prediction:

    iPad2 faster in real world tests than Xoom

    iPad2 significantly faster in real world browsing tests once Xoom gets it's Flash enabling update, and web pages have animated advertisements everywhere. That's the only reason the Xoom appears snappy now...

    I think that it is reasonable to consider the lack of 1080p video playing at launch (for a device with the hardware power to do so) --- a feature slip.



    You can disagree with me on the merit of my argument, but don't take personal shots at me for no reason.

    Utter nonsense. Unless you have some evidence that 1080p video playing, which is a pointless feature, was actually planned, it's not reasonable at all to call it a feature slip. Your arguments not only don't have any merit, they aren't even arguments, just fictional claims.



    And, I'm not taking personal shots. I'm just pointing out the truth that you are simply making stuff. Bullshit is the best word there is for that.

    My first Mac only had 1 meg of RAM - and it still works!

    Now get of my lawn!

    No, I have not done any refragmentation or rebuilding with my new computer. I have not backed up yet though, I should do this soon. I did not have a chance to buy the extra disk yet though.



    I have to systematize the folders in my two external disks first though.

    RAM is very important, if Apple has stayed with 256MB the upgrade would be worthless. From the day it debuted iPad one has suffered from the lack of RAM.



    Well then how much RAM is sufficient?

    I'd wager that they are both pretty fast. I'd also wager that any difference in speed is negligible anyway. I think it all boils down to preference. I'm quite pleased with the marriage between software and hardware that we all love and expect from Apple. I love the emphasis on aesthetics as well as functionality and beautiful software.



    People like you and I comprehend the difference between dual core processors and flash storage. But my mom for example, doesn't give a rat's ass about those things. All she considers is what this device can do. Apple is clear about it's capabilities. You can choose from 65,000 apps - You can FaceTime, PhotoBooth, it has 10 hours of battery life, you can make movies with iMovie, record and play music with GarageBand, browse the web etc.



    Apple's appeal is to a much broader audience - people just like my mom or my grandmother. Even corporations - When you hear about tablet adoptions rates in Fortune 100 companies, it's always about the iPad. Apple will go on to sell millions of these while many of their competitors will be DOA - and it's their own fault. Instead of highlighting the inherit features of their respective devices, they're too busy boasting about processor speed and HDMI ports - things the average consumer may know nothing about.

Plus the fact that Xoom can both play and output 1080p content while the iPad can digitally output 1080p but can only actually play 720p (cleverly presented by Apple, i must say).



    Anyways, Apple is all about the user experience, so until Android makes some serious improvements that get it up to the level of the iTunes ecosystem, hardware is something of a moot point...



    "... get it up to the level of the iTunes ecosystem " You're joking, right? iTune is the most complicated, unintuitive application I have ever used. I would buy my parents iPad if it weren't for iTunes. Apple needs to figure a way to do without this dinosaur.

    Sounds like you need smarter parents. My grandmother handles iTunes with ease.

    Where are you coming up with that? It was long ago dispelled that the paid upgrades were tied to carrier contracts.

    You forgot to mention the reduced battery life once the Xoom gets Flash.
