This is what I'd like to see added:

1. Far better graphics capabilities (no tearing, include 3D effects and animations)
2. Boost in CPU speed (whatever is needed to enable decent [Skype/Gizmo/whatever else] video chats to a PC).
3. Better resolution camera and decent video recording support.
4. DVB TV receiver (or have a separate version of the IT which includes this)

Most important of all is the software though - Skype video, a compelling media browser/player interface, and better contact/PIM applications are needed for sure.
Oh, and Java support would be nice.
