Bioshock - Xbox Demo Live

Word on the street (via Qt3) is that the Xbox 360 Bioshock demo is now available through Live. Rumour is that a PC demo is planned for the end of the month but I haven't seen anything official. From respected gaming journalist Tom Chick:

Don't play the demo! Steer clear. For serious. Go log into WoW instead, or start a game of Civ IV, or take a cold shower. But whatever you do, do not play the Bioshock demo. It will just make the next week sheer torture!

You have been warned...
[...]

Actually, I haven't seen the demo, so I don't know what's in it. But I have played the first bit of the game, and I regret it. My life has been slightly miserable ever since.
