nano 4 gen, in early fall '08. I bought it in the green, because I have a weakness for green in general. I was pretty happy with the color...until the next generation came out and the lineup included a gorgeous, dreamy emerald green that was *exatly* my favorite shade of green
It burned, but I got over it quick because I knew I had gotten mine when I honestly needed it, not just as a random whim - my ancient little creative Muvo from like '04 had finally given up the ghost
Of course, it could be that what made the biggest difference was the brand new iphone that was in my pocket and piping music in my ears when I saw those new ipods
But I didn't stop using the ipod, it actually turned into he perfect setup because I began to use the ipod for hooking into my sound system at home (and in the car for road trips) so even though I got my iphone when my ipod was still fairly new, I still got tons of use out of the ipod. Still am!
