Wireless charging for the iPad3 would be nice,
I hope Apple don't move to a fat 4.3" display for the iPhone 5. The HTC models carrying that size screen look way too large for one handed use.
Depends how big your hands are really. . .
Bring on the large screen! 3.5" is too small and outdated. I want a decent upgrade visually from my 3GS. I'm really glad I did not get a iPhone 4, the res is nice but it's too small still.
It is still primarily a phone, what size screen would you prefer? Surely not something as big as the samsung tab?
Not for me it wouldn't, it is ridiculous in-efficient. especially when you can just have a dock and it slots on.

If it's just a "rinse, repeat, faster spin cycle" I'm not interested. That's all iPhone has been from the 3G onward
Not really, the iPhone 4 was massively different to the 3G - different shape, better screen, better camera, front facing camera - not really sure what other logical changes that can be made tbh

How is it inefficient?
Every single iPad I've seen outside of an Apple store has a cover on, you can't dock with a cover...
Wireless charging/IO would fix this and I don't want to clutter my house with docking stations.
Docks are for desks, the whole point of an iPad is to use it away from a desk
Besides, wireless charging is cool, the technology is ready and Apple needs something WOW in order to sell iPad3.
Because wireless charging is only 40% efficient.
Personally I'd rather use an Ipad with out a cover and use a dock, then stick it in a cover for transporting. If you wnat to keep it scratch free can always get all-round plastic sheet stuff, like for the screen.
