just came across this
http://www.ubuntu.com/devices/android
basically you will able to dock your phone with a monitor, keyboard and mouse and run ubuntu from it, which is tightly integrated with your phone (shared contacts, photos, calendar etc), you will be able to call, txt while using ubuntu.
really really cool idea, i dont see apple ever doing anything like this. windows might do something similar with what i know about their tablets.
but this is kind of a no brainer, makes complete sense, would make me switch from iphone.
