2. If I buy one now, should I buy an 8 gig or 16 gig model? I already have an iPod Classic 80 gig which I'm gonna keep using.
I'm not you, but I'm also planning buying an iPhone and I also have an iPod - but I figured out, if I buy the 8GB model I'll probably gonna regret it later. I mean, it's not just music, who knows what the future holds for space-demanding software. Better to be on the safe side, if you ask me. It's always nice to know you have extra space if needed. And the price difference isn't THAT big...
EDIT: Also, why not just use that extra 8GB for music and then sell your iPod, and then you wouldn't have paid any extra after all?
