Review

Pros: The extra playback hours are definitely a good thing - I'm finding that I probably get around 10 hours of audio playback with my 4 month old 5G.

Cons: The video is still 65K colours- I doubt the new version albeit brighter is going to get close to the Creative Vision:M with its 256K colours (amazing screen quality compared to ipod - it really makes a big difference - the ipod looks washed out and lifeless).
