Between STALKER, Lord of the Rings Online, Sims 2 Seasons, and C&C 3 my PC gaming time has really increased a lot lately.  Not that the console releases have been any slouch either, but it is more clear to me than ever that the constant doom and gloom about the viability of the PC as a gaming platform is wildly overblown.  Sure, it has a smaller market share than it did before the ascent of the modern-day console in the past decade or so, but the just as the PC will never escape some of it's root problems (hardware inconsistencies primary among them), it will always have some inherent advantages like an impossibly large install base, highly expressive input devices, and the first platform for cutting edge technologies. 

Of course technologies first pioneered on the PC (to its advantage) like pervasive networking, electronic distribution and advanced 3D graphics, will make their way to the consoles.  Heck, I love all my consoles.  But the PC is still king in many ways, especially in some of my favorite genres like MMOs, RTSes, and strategy games.  Things may change, but I don't see expect to stop buying PC games anytime soon -- even if I wind up buying them all online.
