PS, Blowout, your backlog argument is moot. I have around 100 games in my PS3 backlog as it is.

So, someone actually sell me a PC...

Total Biscuit, a PC gaming YouTuber, recently did a mailbag episode of "I am a console player; why should I get a PC?" and was fairly non-biased it in. You can find the video here.

Actually..That's what the PS NOW will address. Allowing you to play your gaming back log to any PS system.

Exclusives are pretty much the only thing consoles have going for them.

You can set up your PC to work just like a console. If you only want it for gaming, hook it up to your TV, set it to boot straight into Steam Big Picture mode, connect a controller, and voila! You can also add your non-steam games to Steam so you can launch them from there.

Then there is the sales. I have around 70 games on Steam, and with very few exceptions I never paid more than 20 bucks, many of them I got for 5 or less (And these aren't cheap indies, they're 1-2 year old AAA games). They also give away games for free sometimes. I got the first Metro game like that.

And then there's the graphics. The PS4 can reach around 1.8 teraflops of raw computing power. The latest AMD card reaches 11.5 teraflops. Consoles can code closer to the metal, but this is also making inroads on PC. AMD has Mantle, and NVIDIA and Microsoft are both going the same direction with GPU's and DirectX 12.
Intel also has increasingly decent integrated graphics in their CPU's. You can play most PC games today without a dedicated GPU.They won't look great, but it works.

Resolution is also running away on PC. 1080p at 60fps is normal on a PC, while consoles (esp. XboxOne - neener neener) still struggle to reach even that. The monster AMD card I mentioned is meant for 4K gaming. I would like to see a console try.

Plus all the other things, like surfing the net with a wireless mouse and keyboard from your couch, the ability to access every streaming service and video site, and not just the ones Sony and MS approved. You don't have to pay a subscription fee just to play online. You have access to metric f**ktons of other software. You can read books on it, listen to whatever music, in whatever format you want, and watch movies with no restrictions. Or you could use it to make your own games.

Consoles are meant for one thing, and one thing only. PC's are general purpose machines that can do whatever you want them to do, including beating the consoles at their own game.
