I had a light green 3rd generation nano (I think :P) but I lost it in IKEA so I got an iPod Touch 2nd generation for two years now. I want the exact same one you want but I don't think Apple makes them anymore.
I had a green iPod nano that got stolen and I now have an iPod touch 4th generation but recentl i broke the screen :'( I want a new one for xmas but i don't thing i will get one because it hasn't been a year since i got the last and i had both my iPods for less than 2 rs i think :(
I once saved alot of money a couple of years ago and bought a 32 G third gen iPod touch. Then a few months later. I lost it. But, 2 months ago, for my birthday, I got a new 32 G iPod touch 4th gen. I luv it (: But I guess if I was to change it I would get the old nano. I dont like the new ones, they are so tiny D:
