Something which is not so heavy would be nice. It is uncomfortable to hold for long periods.
Agreed. Any real upgrade would be...
1. The display.
2. The weight.
Anything else is going to be secondary...
(Oh perhaps USB ports?)
And another thing I spoke to the Apple store dood this morning...
Mouse cursor... Im sure eventually the iPad will be unlocked to allow mouse usage (i.e. a step closer towards laptops etc) e.g. magic mouse usage?
