Quote PC all the way. Xbox cannot compete.
And can you supply me with a PC for £120, I think not.... Half Life will be good on the Xbox maybe not as good graphics as the PC, but the On line gaming experience will be better for sure.
Everyone will have voice, no sever's required, and the game will be released without the need for the constant stream of patches you get with many of the PC games.
I have a PC as well but I do all my gaming on my Xbox now, hassle free
That said, you can't get a PC for £120. But can you do...other stuff with an X-Box? For £400-500 you can build a decent machine, which handles games fine but allows you to talk to friends, write dvds, watch movies, surf the internet and much more.
