How do you go inactive in summer? Isn't summer when you have time to play trem?
Our school gives students a tablet pc, and that's how I play Tremulous (same as my brother, Dark/Supra/Tweety/etc). At the end of the year, they collect them, reformat over the summer, rinse and repeat.
I only have 1 computer that's nearly always occupied, and not sufficient enough to play Tremulous (512mb ram, stock graphics card, 30 fps on atcshd MAXED, + shit wireless mouse).
I have better things to do in the summer anyways, I'd only play Trem if it was important, like this.
