The PS2 costs the same really, and I have the offical version of Linux provided by Sony for it... so what is the point in putting linux on an XBox?
Either way, it sucks on both systems due to limited main RAM.
The coolest part is the cable that comes with the ps2 that lets you hook it up to a computer monitor and see things in a much higher resolution. Of course, you can't make existing games go high res, but you can write your own games to play high res.
The only thing I didn't like was how difficult it was to actually figure out how to write simple games. It comes with nothing to really help you out and point you in the right direction, but in the end I can say that if you can't figure it out with the material provided (just search the DVDs) you will never be able to program for it anyway...
