Justifying an iPod nano versus iPod with video purchase

[mikebw]

I won't use my iPod (5th gen, 30GB Video) to workout, it's just too big. Not too thick though, it's nicely thin, but it does weigh more than I'd like to have bouncing around on my arm.

I have used (my wife's) 1st gen 2GB Nano for workouts, and that is a much better fit.

8GB vs. 6GB really doesn't seem worth upgrading to me, and if it's mostly for workouts she should really need that much space anyway.

How about the new Shuffle?
