I'm contemplating a new iPod. The corporate refurb prices are quite tempting right now... I can get a 4 gig refurb nano (current gen) for $145, or a 30 gig refurb video iPod (current gen) for $199. I know it's only $55 difference, but what i'm wondering is if any of you with the 4 gig nano wish you had sprung for the 30 gig? Viewing video on 2.5 inch screen doesn't really interest me... and I have about 10 gigs of music...
