The 7G hasn't introduced any compelling features that would make me want to jump from the 6G Nano. It seems to me that anyone interested in having videos on the go would probably already have a phone that can do that, where they don't have to look at such a miniscule screen anyway. Pointless feature, and my guess as to why they increased the screen size (and thus made the whole thing bigger) The 6G is known for having great audio quality for a DAP, and it's TINY. It's got that awesome little clip that clips right to my seat belt in the car
I was really excited about the upcoming 7G Nano, but I was pretty let down when they removed all the things I love about my 6G and added nothing interesting for my uses. I know now that I'll be looking for a used/refurb'd 6G 16GB Nano to replace mine within the next few months.
On a side note, my 6G nano has been stepped on, dropped countless times, shut in car doors, washed & dried with my clothes, and the screen is shattered with many small pieces of the glass coming off over time to expose some of the underpinnings. It still works like it was brand new, touchscreen included, minus battery fatigue over time which can be expected. They made the 6G Nano TOUGH. I can't argue with a track record like that. It's so small and light, that it's not a danger to itself in a fall. LOVE this thing, I wish they'd improved it on the 7G but at least that'll let me snag a cheap 6G soon.
