I recently bought a 360 and a PS3, but I'm a PC gamer, always will be, always has been.
Console users and PC users go on and on about each other, but the question of who started is like the question of the chicken and the egg. Irrelevant.
I would like to tell you why PC users are pissed tho:
The industry is moving towards consoles, because then they are easier to control and thus, subject to every last piece of thing publishers force down their necks, while neglecting the PC as a platform, because, if a PC user wants to, can avoid a lot of their bullshit, without piracy. Consoles are cheaper to develop for and maintain support, but they mostly hinder a lot of games to be truly great, because hardware becomes a very big limitation in just a couple of years. The new consoles are already worse than mid range PCs, for most stuff, except some tasks requiring high bandwidth physics processing and video capture, since the PS4 includes a chip that does real-time video encoding, but then again, they need that, because thay cannot sacrifice GPU performance for that, because it's already taxed with running a modern game. This new generation is another 720p console generation, unfortunately. Just look at the Unreal 4 PS4/PC demonstration video on youtube.
Publishers will do everything to make more money by spending less money, therefore blame PC gamers for piracy and screwing them over wherever they can. Rockstar releasing GTA IV almost a year later, okay. Whoever is a big fan already bought it in disappointment, maybe even bought a console. Most of the users who bought it on the PC, faced an incredibly crappy port, riddled with bugs, maybe refunded, maybe spread the word, so this way the fragmented market becomes even more fragmented. Okay, they made a bit more money 7 months later, but compromised on the product, by offering an initial inferior experience by only releasing it on consoles and by offering an inferior experience for anyone who doesn't own a console. So see, we bought our hardware, we kept buying out games faithfully and when it comes to us, we're less than 2nd rate citizens, we get shat on, because we are the ones that can be scrapped for profits. Also, misconceptions about PCs: they don't cost that much, if you consider how shitty the initial console rollout was, hardware-wise, buying a PC might have been cheaper on the long run, than buying 2-3+ 360s or 1-2 PS3s. A lot of indies exploited this fact and voila, they sold and made triple A money, while big publishers didn't. The controls: yea, the market is shaped for consoles, a lot of popular titles have become a rarity, like strategy games or RPGs (they have been replaced by ARPGs), or just are plain uncomfortable, compared to how games in the past been. Also, if you dislike the keyboard and mouse and want to play on TV, you need to do exactly two things: plug your PC in your TV and plug your controller in your PC (or the reciever or a bluetooth for the dualshock 3). That's it. I don't really get how that gets harder than using a console. If you cannot be arsed to use a mouse to doubleclick on your games, just use steam big picture, etc. I can download and play a 20 gb in game in 15-20 minutes, so that's also a superior thing.
So maybe a few people are butthurt for a reason. A lot of them aren't. A lot of them are just trying to justify their choice for themselves by arguing with both the other side and themselves.
PC users, talk to console users. Console users, talk to PC users. Don't argue with each other, don't be mad at the other side, enjoy the games. If you want a target to be mad at: publishers are the cause of most of our issues. Channel your anger and frustration at them, maybe? Maybe they really would consider the PC users' side if they heard your arguments instead of the console dude, who can't change anything in the industry.
