i prefer the 6th gen nano as i can clip it to clothing while at the gym. that way i don't need the Shuffle which is a PITA without a screen IMO.
if you've noticed, all apple does is flip flop on the design...going from thin and long to more square-like to keep things fresh and new. they take away features, then re-add them and call them new features. they've been doing this for over half a decade. don't be surprised if the 8th gen Nano resembles the 6th gen, and the 9th gen resembles the 7th gen
All Apple did was add a 2.5" touchscreen, Bluetooth 4, a bigger battery, enhanced Nike+ support.
It's a vast improvement on the 6G.
ahh let's see where do i start. everything you just said are features, not design. and you think a diagonal 2.5" screen is really that great? the 5th gen Nano had a 2.22" screen. guess what - they're both pointless for watching videos which is why they are shaped that way. then they stripped away that feature in favor of a small square clip on design, now they're back to the elongated rectangular design.
i was talking about design. go to Wikipedia and look up the iPod Nano and see what Apple does with the design generations. it's pure genius. basically marketing 101
look man, i didn't mean to strike a nerve with you. i like the 6th as it suits my needs better. my parents prefer the 7th gen nano b/c it has a bigger screen. but my point is that you don't need the newest nano to have the big screen - Apple had it before but they keep going back and forth to create the "all new design" marketing spin
