WOW, people have no idea how technology works in this thread... I am no expert, but I do have a CS degree...
iOS does NOT store multiple applications in memory, or running simultaneously on the processor. You may ask "Then how does it multi-task". The short answer is "It doesn't" in the common sense of the word.
When you switch to another application, the iPad uses the advantage of a solid state drive. It freezes the application and stores its current state to the SSD. This means, what the user sees is a very fast resume and the APPEARANCE of multitasking. While it is true that applications can request to background process, nearly NO app does this. Even calendar applications simply add events to the system scheduler, rather than multi-tasking. It's a brilliant way to give the consumer what they want while preserving battery life and performance.
That being said, only one application and parts of the OS are actually stored in memory. That means, unless you are running a singular application that needs that memory, MORE does NOT help. Like the poster above me, the system-on-a-chip technology has insanely fast bus speeds. Even if the OS has to retrieve information from the hard-drive, it's an SSD, which is VERY fast compared to a traditional HD.
My point: The pauses, slow down, etc. are due to iOS bugs more so than lack of memory. 512MB of RAM is MORE than enough for the way iOS works. The iPhone 4 uses the same chip and has nearly the resolution of the iPad; it works fine.
Well BS that we need to get this info from a fourth party. Further it is BS in the sense that Apple does publish many specs for the iPads but prefers to screw over the consummer with respect to this one important parameter.
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.
It's a good thing you shouldn't attack people here, or someone would call you a clueless idiot.
Funny how last year when people whined about iPad only having 256 of RAM while iPhone 4 had 512MB.
What exactly about making that complaint makes it "whining"?
The iPad having half the ram caused demonstrable performance issues compared to the iPhone that had double - when there actually is a problem, isn't it perfectly reasonable to complain about it?

If you don't think that iOS can get by on less memory, just try running your mac with only 256 megs of ram (or even 512 for that matter).

Don't you think it may have been designed to do that? I normally have 6-7 pages open on my 3GS. Some reload, some don't. I tried it with Safari running in the background and not by killing the process.

I did, see earlier comment.
The "others" that have 1GB of memory also have a generic OS that brag about Flash. Trust me, with Flash you will need all the memory you can get. Also with their 1GB, how's their battery life?
It's more a question of whether you'll be able to use apps written/updated in 2 or 3 years that are designed to run on iOS 5 or 6 or 7.
The iPhone3 and 3G are both noticeably slower when running iOS4 and extremely slow when running apps that were released for iPhone4. I borrowed a friend's 3G (running iOS4) the other day to send an SMS when my 4 ran out of battery, and it really surprised me; imagine if the Macbook you buy today slows to a crawl when you install Lion later this year or when Pages gets updated next year. I think the iPhone and iPad fall more into "computer" territory than "phone" territory in the way that I expect to be able to run whatever programs come out over the next 3-4 years without feeling that they're too old/too slow technology.
I don't know if having 1GB vs. 512MB memory means anything right now within iOS4.3, but I'm almost positive it would make a difference when iOS5/6/7 are released.
From Apple's perspective, it allows them to get under the $500 price point and keep their targeted profit margins, while we can see the Xoom is going to be more expensive, but maybe have more longevity on the per-user basis...
That is if the Xoom will get timely OS updates...
The current state of mobile is akin to the earlier days of PC's. The advances were coming so fast in hardware and software. There is a huge difference in the longevity/usability of a PC/MAC bought 10-15yrs ago vs. today or the past few years.
If you bought a PC 15yrs ago - the software coming out a year or two later would bog down the machine if it would run at all. You buy a PC/MAC today and it is much more likely that software in a year or two will run just fine.
Moot point - the article broadly states "Apple prefers to avoid detailing technical specifications of its devices", which I refuted.
Refuted, my ass. What does Apple say about the A4? That it's a "high-performance, low power system on a chip". A5 is the same, just with "dual core" added to the mix. Likewise, they do not specify which GPU they use.

When connected to a 1080p tv, the Xoom will "actually play" 1080p video. Conversely, while the iPad2 can technically output 1080p, it can only actually play 720p video, even when connected to a 1080p TV.
It can only play 720p video... when mirroring the iPad's screen. There are no hardware limitations preventing the iPad from outputting to 1080p. 9x the GPU power comparing to the original iPad (which produced graphics akin to the original Xbox) also speaks volumes.
Can't wait to get my hands of this thing. I don't care how much RAM it has - My question is how does it perform. From everything I've read, it's a beast.
RAM size is moot when you consider the speed of data between the CPU. A 20MB app running on a 256 RAM has no performance gain running it on 512MB RAM. Performance doesn't increase per RAM size but per data rate. The only benefit of a larger RAM is the amount of applications you can run at once (but then again, iOS can manage this by quitting idling apps), the maximum canvas size of photo editors and how many layers it can hold, etc. The #1 bottleneck is retrieving resources from the storage. But it uses SSD which is fast.
I'm a Video guy and I am still shocked how you can edit HD movies on device, smoothly.
At least everyone should be happy now that it has LPDDR2.
Don't you think it may have been designed to do that? I normally have 6-7 pages open on my 3GS. Some reload, some don't. I tried it with Safari running in the background and not by killing the process.
Designed to intentionally reload the same page instead of just caching it and bringing it up instantly? Why would you design something to be slower and use more bandwidth.

News flash - the iPad 2 hasn't shipped yet. Maybe 512 will be enough, maybe not, but we don't know if there will be complaints when it shipped. Despite the millions sold, there WERE plenty of complaints about the original iPad, one of the biggest being bad user experience due to not enough ram.
News Flash:
Just because you think there were plenty of complaints doesn't make it so... besides, even 1000 complaints (and I highly doubt it was even that high) set against 15 million sold...
Apple makes exceptional IOS devices. I have owned an iPhone 3GS and currently own an iPhone 4. Bottom line they were both great. My jail-broken 3GS would play 1080p files. There was no good way to output them outside of the iPhone and 1080p was overkill for a iPhone 3GS screen. However, with the iPhone 4 it can output 1080p not only 720p video if it is jail-broken and using an adapter. Apple makes their products to work the combination of components and their operating system works. They do not put out trash. You can complain about performance that no one has experienced with the iPad 2 based upon your thoughts of specs, but it doesn't matter if it does the job well and I am confident that the iPad 2 will do it's job well as all of it's other products have done well.
Technology does get outdated. I sold my iPhone 3gs for $250 2 years after I purchased it. They hold their value well. You can always sell your old and buy the new model. You probably won't get what you paid for it, but you could pay off a very good portion of a new unit. Is the iPad 2 an improvement it appears very much so. Will it be better than some other brand tablet, IMHO yes. I trust Apple products and have some friends with competing products and the same friends want to switch over. User experience is important. That's not to say that Apple is perfect, I think they block things that they shouldn't and limit their devices where they shouldn't in connectivity, but they make the product, not me and I'm still very happy with my experience.
