"A "killer feature" for me is something other than taking pictures and video, running apps, making calls and texting. I have yet to find a phone that has something besides these 5 basic features."

The phone that slides into a clamshell laptop unit and becomes my laptop, with appropriate blended features. Acer has prototyped it, and a couple of others, I think, but the time may have come. Tablets are doing it, but there's probably still room for this to work.

'Course, Apple's probably got this already prototyped out somewhere and will be dropping the iPhoneMac on the world about two years before Microsoft can react....
