No talk about Windows Media Center? I use it all the time on the 360 to watch and record live HDTV streaming from a PC.

There's some games that have better gfx on PC but its not always the case if you get a game that was designed for the 360's hardware then it might not look that great on PC. Lots of those games don't even get ported to the PC side. I remember the first HALO took a long time to come out on PC and when it did there was some frame rate issues. So don't blast the consoles in general because one game looks better on the PC there will always be some games better on the PC some other games going to be better on the consoles since they don't have exactly the same hardware.
