Same old arguments and its normally by people that can't run their pc's.
Frankly you buy any old dell machine, never update a driver, 99.9% of games will work without a single issue ever. Its mostly the people that update to every single new beta/full driver that get the problems new drivers have with games, plenty of older stable drivers never have any issues with anything.
PC gaming is FAR from expensive, at this point in time I literally don't know anyone, from my 80yr old grandma, to anyone I meet, who doesn't have a PC anyway for everything none gaming. Stick a £70 gfx card in that machine and you instantly have a machine more versatile, cheaper, and more powerful than any console. Expensive, only idiots think that, its cheaper, always has been, always will be.
Yes an entire uber powerful top of the range pc is expensive, but again out of most of the people I know, they'll buy a family pc every 3-4 years at most. a 3-4 year old pc will have a 2Ghz plus dual core at this point, and so a £70 gfx card, hell a £40 gfx card gives you a lot of gaming power for next to no effort. Even if you take your pc in to the purple shirt brigade and have them stick that £50 card in, its a case of walk in, pay, and walk out with your upgraded computer.
But these days, well, i've put in new bits for many friends of familys, most people know a "computer guy" who will help them out for nothing, or peanuts, so its between free and ridiculously easy, or a trip to the local computer shop and very little cash and pretty damn easy, to upgrade any computer.
Your average user who doesn't upgrade every little driver every 8 seconds of the day will have less problems than over enthusiastic people who have to try every little new thing that happens.
Thats all pretending that consoles don't crash, need updates or die, of which, all three happen.
At some point both the normal PC and console will be dead anyway, it will still be PC's but every household will have a "server" room with a single pc with a 16-32core cpu with virtualisation. a bunch of family members can browse the net on wired/wireless screen's, mice, keyboards, controllers and can all use the same comp at the same time, gaming downstairs on a big screen, or upstairs on a smaller screen in your room, whatever.
