This topic has often appeared in other threads and posts; also, I'm new to the iPad2 (April purchase) and enjoy the device but coming from the PC world, I would certainly like to have other options (other than games which I play few being from the older generation) - just to list a few below (and most of these have already been topics of discussion):
1. Input slots, such as USB & SD (and to accept files other than images).
2. Open file system on the iPad and also an icon on a computer.
3. Much less dependence on iTunes (for numerous reasons).
4. Better web browsing (I do miss those right-click menus).
Well, I'll stop there and will be quite interested in others' responses - now I've not 'jailbroken' my iPad, so not sure 'how many' of the above listed could be handled w/ ease or at least in part -
