Consoles persist because people are too stupid/lazy to learn how to buy and maintain a computer. However, as consoles increasingly become shitty, poorly constructed computers, this advantage is disappearing (google "Skyrim Save file" for one of the many examples of architecture and coding fail on consoles). I can see the advantage of a console like the N64 where you pop in a game and BAM it's playable. But the modern console isn't that, it's a shitty computer; complete with outrageous loading times, constant software bugs and hardware failure.
Massively modable deep-content games are absolutely the ONLY GAMES I could give a remote damn about playing. They're also completely unplayable on consoles, and usually not even available (Romance of the Three Kingdoms is an exception, and it's still 50x better on PC).
I need to be able to get new content, scenarios, countries, models, skins, weapons, etc. or I don't give a ****. I need to be able to mod it myself, and get user content, without the mediating hand of shitty architecture and stupid *******s at Sony freaking out because someone might hack their overpriced paperweight.
Fighting games, JapRPGs, shooters, MMOs, etc. put me to sleep. I would literally rather do nothing than play them, and this is exactly what happens whenever my friends start playing console games. I want single player/coop games with intense depth like Hearts of Iron 3, Witcher 2 or Minecraft. Anything else is less interesting than mowing the lawn.
I also don't own a television, because televisions have shitty resolution (a CRT from 10 years ago looks better than your 1000 dollar TV), and anyway, only *****s watch TV.
Also, my computer doesn't browse the internet like a retarded kid on the phone book, it doesn't freeze every ten minutes on Youtube, and it's capable of connecting to the wireless internet at more than 1/10th potential speed.
