I've found myself, perhaps 5 or 6 times over the past weeks, needing to print a doc that I just created / changed on my iPad. Getting over to my MacBook to print is a bit of a pain.
As far as camera - no thanks! I keep my iPad in a sturdy case - I would hate to have to remove it from the case every time I need a picture.
More memory, faster processor, bigger screen - don't need em and wouldn't want them. Multi tasking would be nice and it's coming (in some form) fairly soon. Also the file management will be good.
I think, reading the comments I see on this board, most people are happy with their iPads. I hear some of the frustrations re the wifi - but it's fairly easy to discount those if our wifi works well.
