1. i like the games better
2. pc just can get buggy and games are older than the xbox (halo 2)
3. ps3 is just a good blu ray dvd player. not really for games idk.
4. and you can add linux on xbox 360 to surf web and everything.
and btw i do have halo 2 for vista... crap... like i have a fast video card, brand new $1500 pc and still is crap. but i guess its easier than getting a xbox if you keep bugs and viruses away from your pc. i just use a xbox 360 controller and play halo 2, fear, and call of duty 4
