iLounge seems awfully sure Apple would NEVER use such obviously "wrong" proportions for the new nano. I disagree: people said the same about the current video iPod--they said the new big screen looked all wrong in proportion or something. It's not "wrong"--it's DIFFERENT, and change always comes in the end 
I find a nano like the mockup to be believable. Wider yes, maybe even larger in volume, but shorter and worth it for the screen.
Re wireless synching... I don't care
I have to plug my iPod in to charge anyway. When I do, synching is automatic. And takes seconds--much shorter than even a partial recharge. So wireless synching would to little to improve my life (and would in fact shorten battery life). It's a fine option is anyone wants it, but I don't.
I WOULD use it for data transfer. (Just like I liked how the old Shuffle could transfer files with no cable.)
