Get a modded Xbox

We're not entirely sure how legal this, but a company called FriendTech is offering to take your Xbox and mod it with a faster processor, an S-Video out port, and extra RAM to turn it into a digital entertainment hub that can play audio and video files (you have to add a hard drive yourself). If you actually want to play games on it, you just flip a switch and you it turns back into a regular Xbox. They'll also just sell you one that's already been upgraded for a little or sell you a kit if you want to try and do it yourself.
