I fully agree with this guy that MS sacrificed the PC market for its own good. There was a list of games that some one put together once showing the decline of awesome PC games right around the time that the first Xbox was announced. It started with titles from '97 to I think '04. Games like Starcraft, Thief, No One Lives forever, and Morrowind were all in production before the Xbox was announced. After the Xbox came out, the number of epic PC titles started dwindling each year until you were pretty much just left with console ports.
If you need more evidence, just look at the PC game controller market. When the Xbox launched, MS, who was arguably the best gaming hardware manufacturer stopped making their gamepads and joysticks. I remember buying one of those force feedback joysticks, and the damn thing doesn't even work anymore because MS stopped making drivers for it on XP. It was the gameport version and now my gameport doesn't even work on Win7.
I used to fanboy consoles in my sig. Now I'm not so sure they are worth my love. Steam has done more for me than all 3 consoles combined this gen.
