The screen should be about the size of a 3x5" card with a minimal bezel. The other dimensions could be taken from my N810 - about a half inch thick and around 8 ounces. Inside I want the equivalent of a 1.5 GHz Intel Atom (although 2 GHz would be nicer) and I want it to be x86 compatible. I want a second processor to handle telephony. I want to run an x86 OS (whatever animal Ubuntu is up to) and a telephony OS (Maemo 6?) in parallel with the ability to switch off the x86 OS and CPU while the telephony OS and TPU remain in standby to handle incoming calls. Slap on 2GB of RAM and a 64GB SSD (shared by both processors) and I'll be happy. Make it happen.
