The Significance of a USB host

For the last 2 years, I've been saying to anyone willing to listen that the future of computing is a incredibly powerful phone that you cradle when you get home or at work, etc. This cradle has a mouse, a keyboard, a large screen and a good sound system.

Android enthusiasts seem to have taken another step to making this vision a reality. Notice in the video that he launches X-Window with a desktop environment from his phone that isn't the Android shell.

That being said, the Nexus One, as powerful as it may be, still isn't the all powerful phone I've been describing for the last 2 years, that phone still doesn't exists.
