Is The Xbox The Cause Of The PC Gamer's Downfall?

Thanks to GamerDad for its editorial discussing whether the Xbox has grabbed much of the development effort and talent from the PC gaming scene, with the author arguing: "From what I've been able to gather, there just isn't much interest in PC games unless as an afterthought to a console release. Deus Ex 2 and Thief III are superb examples of this mindset." He continues of the Xbox: "Its introduction has clearly robbed a lot of the resources that used to be dedicated to making PC entertainment. This is fine if you're willing to buy an Xbox and support Microsoft directly that way. It's not fine if you're a PC gamer that wants what the PC can offer specifically, and not some watered down version of what you've come to expect from a company." Do you agree?
