True. Most of the games I want to play are closed source, though, irrespective of platform, so it's a bit academic.

Sure, I just thought 'easy backward compatibility' in particular was a misrepresentation of the current PC situation. As long as you're not talking pre-Win95, the old contrast between console games that 'just work' and PCs needing post-release patches, good luck on IRQ conflicts and a comp-sci degree just to get running is long out of date - more recent consoles have started seeing firmware update and patch issues of their own, and modern PC games should run for most users on default settings without problems, stupid DRM allowing.
I actually think one of the nicest things about the PC platform, a benefit of general versatility, I guess, is its tendency to be able to emulate everything else, sooner or later. Piles of old plastic and trails of tangled leads for the sake of one or two games you still want access to on older consoles are a pain in the ass. XBLA/PSN/VC seem like they might be offering some reasonable competition on that front, though.
