First off, I was motivated to type this because of the numerous over-generalizations made about consoles mostly by some PC people as well as some websites. You see all these articles about how you can get a PC for not much money and it'll still run games better than consoles. And of course, there's all the bragging about steam sales and such. Yet, when you boil it down, many of these people miss a few key facts:
Consoles are still more cost effective. For $400, you're not simply getting hardware. You're getting the ecosystem that comes with the console and console communities are just as good, if not better, than PC (modding is a nice idea, but that's pretty niche). You also get a controller which itself costs around $50 or such. Yes you do pay have to pay for online now but with PS+ you get an incredible deal with plenty of value (and let's face it, if you game on PC you're spending quite a bit of money on hardware and games anyway.)
You're also guaranteed a system that can play the games that you buy. With PC, there's always that chance that a) it wasn't properly optimized for PC b) you're hardware can't handle it or your computer has some internal/software issues c) the game that you bought was not even complete to begin with (which happens way more often on PC than console).
By far the greatest reason why consoles still trump PC is that you don't need to be online to play a game. I can play a campaign without needing an internet connection. How is that 95% of PC games now require steam/drm? I can't even access story mode unless I log into steam in most cases. Even when you buy a physical copy it still requires access to steam or some other platform like origin or uplay.
There's also the whole "steam sales" thing. Consoles, especially PS4, have already come around to their own sales and many games can be found cheap about a month after release. PS+ also gives you an additional discount and you also get a couple a free games that are, for the most part, still pretty recent.
And finally, console and console games are what typically drive the industry. When do most developers start shifting gears on new game development? Around console cycles, not PC. And with the success of PS4, and to some extent X1, you will have developers focusing on consoles first. I mean, look at what happened with Watch_Dogs. It'll be the same thing with other games as well. I bet Grand Theft Auto 5 will be very similar between PC and next gen consoles.
So there you have it, a pretty damn good reason to have faith in consoles because they still rock.
