There is of course the obvious to the statement "What you can do with a Xbox", but what I'm talking about is using a Xbox in another more practical way ;).
Technically, the Xbox is a legacy-free (i.e. not based on old technology) PC by Microsoft. The hardware under the hood is:
The good news is that the Xbox is very USB-expandable. You can interconnect 216 USB devices from one PC - including a few hubs, of course. You can connect anything to the Linux Xbox and it'd work a treat as a server or stand-alone PC.
Because of all the above, you can turn it into a regular PC - without loosing the Xbox's gaming and DVD-ing.
I'm sure it's been tactically worked out by Microsoft to be unable to run Microsoft Windows, even though Xbox is based on a shrunk-down version of the Windows 2000 kernel.
The good news is that Linux (pronounced Leen-ux) is a fantastic operating system which does work wonderfully with the hardware.
I am currently mid-project, but as soon as I can I'll put some notes up here!
Surely a £100 computer that plugs into both a TV and a monitor is a good thing. And since it runs an extremely flexible operating system, there's no limit to what you could do with it.
