I got the 16gb iPad1 and 2, and with the amount (and size) of useful apps, some email, books, and mags, 16gb is now not really enough. Every time I see the app update notification light up I cringe cause I know I'm Gunna have to find ways to free up space in order to simply update what I've got.
...I'm going for 32gb next time.
