The only way I'll be purchasing the next iPad or any thereafter is if a microsd slot is included. If not, goodbye future iPads or iPhones for me. I'm done with IOS devices otherwise... Do you think iPad 9 will include an expansion slot? I'll be purchasing that one.
512 of RAM for iPad 2 is not acceptable. Much less for iPad 3. Are you out of your mind? I had to sell my iPad 1 due to its inability to work properly with iOS 5 I'm guessing due to low ram at 256mb, and lack of being able to reverse to IOS 4.
You will never see an sd card on a future iPad. That's one of those "that would be nice" but know it will never happen.
