FaceTime, especially for :
- families (let grandma see the kids playing)
- business conferencing (quick shot of the white board with dodgy sketches)
it's purely a convenience thing, but something that you can get used to having real fast.
yeah, but since I have to cameras in my mobile phone (now just one) since 2005/6 and I only used once the front camera, and very rarely the front camera, I don't see them as compelling features.
I think the gpu+cpu+battery are way more important.
