Also, make sure it comes with a projector and a coffee machine, but proper espresso one, not that filtered stuff.

On a more serious note, I doubt that 1080p makes sense on anything as small as a 4-5" screen. Then again, and depending on the technology behind the interface for the other half, we may have a bigger folding screen - the technology for that is out there, not commercialised [as far as I know] but it is there.
