So judging by the OP we are not bound by practicality, feasibility or wide appeal more just make a system for tech heads and gadget freaks like me.
So for a start it would need a opaque (as in can't be seen through) multi-angle hologram projector capable of projecting a fully realised 3D scene up to at least 1 cubic meter, and capable of projecting a flat screen for personal use and text, video and classic games etc.
The ability to use the cell phone network anywhere in the world to download apps and other media from the store without paying a carrier, sony would pay the cell phone networks a % of all sales.
an 80GB HDD like the ones used in the iPod classic.
a pair of 3D cameras (front & back) for gesture and facial tracking and augmented reality plus 3D home movies.
Fully featured web browser.
and that should about do it...
also who was surprised by the the 3D reveal at E3? The screen was practically confirmed months before.
