Considering most competitors have 1GB of RAM in their tablets, even 512MB is low.
1GB already is pretty much standard. See the
engadget article comparing the iPad2 vs the competition:
I know RAM isn't everything, but I
SERIOUSLY doubt adding an extra 512MB will make things more expensive or hurt either Apple or the consumer in any way.
Hmm... Let's just suppose the iPad 2 is 512 MB. The chart you quoted would be one reason why Apple might not want to disclose the amount of memory -- because of the
perception that even 512 MB is not competitive with those other devices.
The fact is iOS is VERY efficient, so it makes far better use of its memory than those other devices. So 512 MB on iOS would almost certainly be better utilized than the 1 GB on those other devices.
My point has been that despite how efficient iOS is, there is a point at which there is no getting around a shortage of physical RAM. At 256 MB, iOS 4 is already a bit cramped. At 512 MB, it has a lot of head-room -- more than half free.
From what I can tell, with 512 MB of RAM, the device should perform better than those other devices that have twice that amount of memory.
But if the iPad 2 only has 256 MB, then THAT's too cramped.
512 MB would be fine; 256 MB would cramped.
1 GB would be "nice" but is probably overkill...well except that even on my iPhone 4 with 512 MB of RAM I run out of physical memory after about a week of normal use.
I am in the habit of rebooting my iPhone 4 every 1 to 2 weeks to free the memory.
I wouldn't even be participating in this discussion if we KNEW that the iPad 2 was going to have 512 MB. If it only has 256 MB, then it will be a deal-breaker for me.
I mean I expect the iPad 2 should do at least as well at multi-tasking as my iPhone 4 -- so if the iPad 2 has half the memory, then it's just not worth the money to me because it will be LESS productive for me than the iPhone 4.
How could it ever be okay for the iPad 2 to only be capable of LOWER PRODUCTIVITY (less multi-tasking, less memory to open large documents) than the iPhone 4? It would be absurd.
Apple has to be smart enough here to do the right thing and put (at least) 512 MB in the iPad 2!
