Plus you can use all the development kits, theres a lot more support, dedicated servers, Lots of mods, etc.
Why not blow money on a PC which can do everything, and run next gen games, and watch tv/movies/music etc.
My school laptop doubles as my gaming PC, and ive yet to run into any problems, and still have a great time.
And to be honest, Xboxs and PS3's are just as hackable as a PC games. Problem is, without dedicated servers, there are no serv admins to ban the hackers on those systems.
I have buddies who run aimbots, and speedhacks all day on console.
