i have the xbox (original) set up on a 14inch portable tv in front of the threadmill,
i run over 3 miles (@6mph) every day trying to get past a stage in halo2,
sadly i finished it , and I can't find a game that gets me excited enough to keep me going, so I have only ran 4 miles in over a week, might un-mod the console and buy halo2 to play it online
i got a 1 month trial free with my 360 (which is only used as a mediacenter extender), hope that will work with it
