Well, the 16gb has the advantage of coming in white.

But like most of the sifu's here, I don't regret getting the 8gb over the 16gb. Honestly, the only thing that takes up tons of storage space is video. I'm at 500megs for mp3's, 1.5 gigs for apps, that's still 6 gigs of space for video, more than enough cos you won't have enough battery to play all 6 gigs on the road anyway.

Uh ok I posted a few weeks ago that 8gb was enough for me ... now I'm not so sure.

I've started putting up a lot of TV shows to watch on the road on my iPhone and video takes up a LOT of space. Just got a few chris rock specials and half a season of Chuck and already the 8gb is used up ...

Do you actually listen to all 16gb of songs though o_o

I only have a few hundred megs of music on my iphone. My entire collection in my PC is like 40 gigs (been collecting since the days of dialup, aha), but 90+% of them I don't listen anymore so I never bothered putting it on my phone.
