I think the most important thing here is the 'docking' and peripheral standards/protocols.
* wireless charging - just set the phone on the right surface
* wireless keyboard and mouse (bluetooth is sufficient, I guess)
* wireless display (isn't Intel working on this?)
* wireless networking
This way I only have to walk up and set my phone down, the screen comes alive, I grab the mouse and I'm online before I can click anything.
I perhaps should explain "wireless networking" - I'm wanting a wifi connection, or even shorter-range connection, that gets me from my phone to a wired link. A mini-WAP that perhaps integrates into the monitor and has a cat5 cable heading to the LAN.
I definitely don't want to be plugging in and unplugging a million wires, prefereably zero! And I don't want cell-data speeds or charges to apply when I'm "docked" - it's got to be dead simple.
