Anyway, I bought an 8GB nano as a gift, and it arrived this morning (Wow, it arrived in about 24 hours to NZ - THAT's Service.)
This thing is gorgeous. I like the proportions a lot better than the older nanos, because it seems more and more like it's just a screen and controls - that is, the battery, and other things are basically 'invisible'. I think that's what Apple was going for -here is a multimedia device that plays allsorts of stuff, videos, music, photos - and all it is is a screen with controls. It's like it doesn't even have a battery or storage, it's so damned small.
The screen is gorgeous, and the new interface is pretty snazzy. Don't know if I'll upgrade my own iPod 30G, since all I'd get is coverflow and the new UI (ALTHOUGH, I could sym-link directories on to the storage part...hmmm...can you sym-link the iPod photo cache onto the drive portion of an iPod? I'm short on HD space on my computer...).
The aesthetics is really nice. I'm a fan of the metal finish (I don't mind the stainless steel back), and the small curvy nature gives the nano a bit more of a 'girly' appeal (c'mon, real tech geeks get a man-sized iPod).
The new nano is a great device - if you don't like the design over the old one, it's at least a lot more versatile a machine with video playback, and slightly more useable photo viewing.
