Check out on the new MOTOROLA ATRIX 2 which does support the lapdock function. Where you just plug it in, and it function like a netbook.
In term of spec the Atrix 2 will feature a 4.3Inch qHD display, 8MP camera with LED flash, 1GB RAM, 8GB On board storage with of course an expansion slot.
The brand new lap dock, will be a slight reduction of the 11.6inch screen to a more standard 10.1 one. As for connectivity, the lap dock no longer requires the phone to be docked into it, rather connecting it with a cable too, letting you possibly use compatible Motorola devices with it too.
So be looking forward to it..
