I own a 20 GB 3G Ipod and I've had it for over a year (unluckily I got it the day before the 4G came out)It still works fine and I haven't had really any problems with it. I wasn't even thinking about buying a new mp3 player, until i encountered the Nano. Should i wait until my older ipod breaks down and then get a nano which may have higher capacity, or should i just get the nano now. I know it the answer souinds obvious, but i am really tempted to get the nano now. And also how long do the 3G ipods typically last?
