PC because it's cheaper for me. And I don't mean because PCs are cheaper than consoles. I need a computer, period. I need to type and print stuff, I need daily access to emails, I need access to internet banking. It's cheaper for me to buy a computer and play games on it than to buy a computer AND a console and play games.
By this stage if I had to get used to a console I probably could after a few months of inexpert fumbling, but I wouldn't like the process of becoming an expert console user and am used to mouse and keyboard by now.I play Skyrim on a laptop with keyboard and mouse, and am perfectly content with it. Sure, I could do complicated things and spend lots of money to make the graphics more impressive, but I have better things to do with my time and money, like play Skyrim and buy DLCs.
I do have to say though, I've seen some incidents of arrogance and condescension in YouTube and DeviantArt comments which shocked me. If a person mentions as an aside they play on a console in a discussion about something completely different, it is not polite to instantly start telling them how ridiculous playing on consoles are when PCs exist. Personal preference means preference of you personally as an individual, not the entire world. The entire world doesn't think the same as you, PC trolls, deal with it.
