Use the Galaxy Nexus as a desktop computer
The video below is a demonstration of how you can use a Samsung Galaxy Nexus (or any other handset with video out) as a desktop computer. The Nexus is perhaps the best example at the moment with its ICS capability and powerful processor. The same setup with a Samsung Galaxy Note could be good as well, perhaps replacing the need for a tablet in some cases. This is certainly the road that convergence technology will take as phones become more powerful, working from one or two devices in various locations/setups.
