I must admit, I love the look and feel of the new little iPod Nanos and was very tempted to try it out. But I just can't stand being locked into iTunes and the iPods don't have the greatest audio quality. The Creative Labs line of MP3 players on the other hand have great audio quality and for me at least, it's always all about the music. I've owned 5 ZENs now (and all 5 still work) so I went with the Zen 16GB version. Here's the sum up for me at least:
iPod: Well constructed, cute (several colors to choose from), trendy, TONS of aftermarket stuff but only 8GB, no expansion slot, locked in iTunes (doesn't work with other subscription music sites), smaller screen than the Zen.
Zen: Buttons not as nice as iPod click wheel, comes in black only, 16GB with SD expansion slot, larger screen, compatible with subscription music-to-go services like Napster and Rhapsody, excellent audio and video quality.
If you're young and trying to be trendy or you're used to iTunes and all that proprietary stuff than the new Nano might be for you - although I think the new iTouch is going to be the new, hot 'cool' item this season.
If you're a little older, don't like the whole Apple thing and just into a quality listening experience then the Zen - or many, many other choices out there - are a better way to go than the iPods in my opinion. CNET is raving about the new Zunes too but I stictly wanted a flash player and 16GB is more than enough for me especically when coupled with Napster-to-go, the service I chose.
There also seems to be a lot more problems and issues with iPods from the posts here but I'm sure a lot of that is probably just that there are SO many more iPods sold than all other mp3 players combined and is strictly a statistical thing.
Which one wou you choose?
