I'll address your last point first.
I did not bring the PC into this discussion, I merely remarked that it is somewhat natural given how graphic focused these threads are.
Other than that I will say that if you have serious usability issues with PCs then you must have trouble functioning in modern society, given how prevalent they are everywhere.
If you were talking about another kind of issue related specifically to gaming, I would say that these are massively overstated by people who don't own a gaming PC.
I do agree that we should try not to derail this thread too much with this topic.
1.) yes, I AM speaking specifically about gaming. usability re: making spreadsheets and posting to facebook isn't really relevant. why bring it up?
2.) I have a gaming laptop. Hate gaming on it because usability is an issue. bought it for Diablo, played it for a couple days, threw the game out and haven't bothered since. I've booted PCSX2 up out of curiosity a few times, but really don't have the patience for that either.
when discussing "usability", console fans typically want a platform where they can just buy whichever game is labeled "ps4" or "xbox one" without having to worry about minimum or recommended requirements. This is a usability issue.
when buying a gaming platform, having to think about the difference about whether a radeon 7700, 7900, Nvidia GTX570 or GTX590 is preferred is ALSO a usability issue.
having to wonder whether a favorite game will support a controller at all is a usability issue.
having to tweak settings or download drivers to get games running acceptably on my specific hardware is a usability issue.
Money isn't even the point. my time is short and I have better things to do with the limited time available to relax while gaming. These things may seem minor to you, but many people don't want to bother. Saying they are massively overstated is false, or no one would buy a console. Why would they? Performance wise PC is always superior after a year or two.
but yeah, derailing is inappropriate.
