At the moment i'm going towards PC simply because my xbox can't find my flat's wifi...
The thing I don't like about the consoles is the amount of restriction, one of the reasons console games are so expensive is due to the commission Sony/M$/Nintendo take per disk. There's also restriction on devices you can use. I have a G25, for a long time it was the only real way for the mainstream to get 900 deg rotation, 6 speed and 3 pedals... so with forza 3 we're told we have to buy a fanatec which is more expensive, yet does the same things. If you want a wireless controller it has to be manufactured by MS, if you want wifi, it's a MS adapter, If you want a bigger HDD its a MS one.
I do prefer the social side, given more people use headsets online, so you can actually have conversations rather than talking with text, which is partly how us staff members get along so well, because a keyboard is never as good as talking. I also prefer the ability to do local multiplayer too, as no-one really crowds around a PC at a party to play CoD/H alo.
