I hope not..there are situations when a touch screen is just not working right. Sometimes you just can't look on the screen and change the tracks or don't have two hands free. When I am biking I love to handle my Nano just with one hand with almost not looking on the screen. And when I am running, then I also have to concentrate on the road and I don't really want to use all my two hands and my eyes to change a song.
A friend with an iPhone told me, "you can switch tracks with the button on your headset". Well I am using Sennheiser headphones and not the Apple ones and sometimes I don't just want to "change to the next track".
(a workaround would be to make a playlist prior running, but mostly I am deciding on my way, so it's not the best resolution.)
For me it's sometimes handy to actually have a click wheel.
And coverflow..it' tacky and nice, but how useful is it really? Maybe I am old fashioned, but when I am looking for the tracks/artists, I go for an alphabetical list and not flicking through any covers. And If I want some random music, then I just let the shuffle mode do its job. I am not seeing me in any situation using coverflow.
That's also my question..I didn't see them abandon the "long" desing in favor for the "fatty" one until it happened. The Nano G2 fits perfectly into some smaller pockets where the Nano G3 couldn't even think off.
I am open for a practical design change, though it would remind us off a Zune (which I've never seen one in the wild here)
