Against everything above, I'm a CS major. I'm into xbox development. I'm into djing/electronic music. I'm thinking about *something* music-related, possibly a port of a synth, possibly more. The xbox looks like a great tool for the music scene and so far nothing's been created. Linux is an option but I don't think it's the best one, for speed & overhead issues.
tv screen? doesn't really matter. anything useful should have every command mapped to a button, or over midi or something. you don't want to be trying to do a smooth cut and depend on how far the thumbstick moves the cursor to click and drag the thing. Bad idea.
Anyways, only problem is my lack of time right now. Same old usual story, but it's true. midterm season, etc.
anyways, I'm looking into it. Until that, you could try some xbox-linux stuff. <
