In the same way that you can get hi-fi systems that act as an amp and speaker system for your ipod you will dock your phone and use it as the processor for your workstation.

Ubuntu have the software for that already - but they need to get a phone vendor on board.

You can already plug an Android tablet into a monitor, keyboard and mouse - but the applications are a bit lacking compared to desktop software.
