[quote name='muhsheesuh']2nd gen is slimmer, has an external speaker, Nike + built in, Genius feature (no idea), and I hear that a new auditory chipset was put in improving the sound quality.
I haven't had an Ipod in a while so I was a bit unsure but, do newer Apple Ipods support East Asian languages? I know the newer Zunes don't so that drove me away from buying one.[/quote]
first gen also has genius and Nike, just no speaker and that speaker is piece of crap lol i tried it at the store and i could barely hear anything lol. And it isn't that much slimmer than the 1st gen. i'm settling for a 16gb refurbished from apple.com =)
