Gavin, in the same token, you can't dismiss a problem as not being universal just because you have not had that problem. The fact is that such issues do enough damage to PC game sales that customers switch to a console because they don't have to put up with buying a game that doesn't work, even though it meets the required specs.
Agreed that I can't dismiss that there is a problem, but I don't think issues with pc-gaming is what's driving the console numbers. Talking about myself and my pc-gamer friends - there is some bitching on occasion about issues, but no one's ditching their pc's for consoles. Although they are buying consoles in addition to their pc's. I think we need to remember that there are more gamers now compared to 10-20 years ago, so it's not just an issue of conversion, a lot of the numbers we are seeing are new gamers. Maybe PC gamers are as numerous as ever, and it's just that there are more gamers overall because consoles created a new market. I think that even if I'm not spot on with this, that it is definitely true to a degree. It is the case that the numbers of computers per household are way up, looking at figures I see about an 80-100% increase in computers per household over the past decade. And console numbers are way up too. Neither of these facts is surprising. And they are not contradictory.
Many people will buy a console because of cost, ease of use, and the casual nature of the equipment, how it's installed, where it's used and what it looks like. And I can see that you are saying that yourself about ease of use. So we agree on that, I just don't agree that the issues with pc games are so bad that they are what is driving console growth.
Edit : And I think getting access to exclusive titles may be a big factor in console ownership.
