As it stands, though, I firmly believe the biggest issue with incompatiblity problems and issues like mostly in the hands of the user. Now, I'm not going to say PC titles don't have problems - that's been an ongoing issue since Pong. Granted, today's bugs and glitches are nowhere near as catastrophic as they were, say . . . 10 years ago. But, the fact remains that the majority of titles (the one's not "rushed out the door" at least) are relatively bug free, with the occasional quirk. On the user end, though, is a whole different story. There's still a massive percentage of the market using "antique" hardware, and a larger portion that don't keep up with software/OS/driver updates. Spending time on numerous tech and game forums, I can no longer count the number of users who were able to fix the issues simply by updating their video, audio or chipset drivers . . .
But, I think the problem there lies in user ignorance - too many users don't know if and or when they need to update their drivers or software, most don't even know how to go about checking . . . ganted, auto-updating utilities make it easier, especially for those who have no idea what hardware they're actually running, but it's not fool-proof, either. The industry as a whole really needs to find some way to address this problem, IMHO, as it continues to give every-day usage of the PC a bad reputation. It's what has lead to users believing that programs don't work, or they're going to have issues, etc. At the same time, there needs to be an easier way for the user to determine what hardware they have, if they need to manually look it up. This is where a lot of pre-built systems fail. The big manufacturers only stout basic numbers instead of providing some kind of "spec sheet" with their systems. Users only see on the box: 4GB memory, 320GB hard drive, 2.4GHz Intel CPU, ATI HD4000 series, etc. There's no way anyone could figure out what kind of updates a user would need from such spec "lists."
Whatever, though - I find it funny. The gaming market has been stating for 20 years now that PC gaming is dying . . . at the same time, consoles are becoming more and more PC like with each generation. I'm simply waiting now for confirmation: the first console that provides a keyboard and mouse out-of-the-box so that you can use a word processor that's bundled with the console
