It's more fun on console. Mouses and keyboards aren't as much fun.
You can use a 360 controller on the PC. It's literally plug and play.
You can also connect it to your big screen TV.
PC can do everything your toasters can do.
Also, M+KB is a preference. It's better for FPS and RTS but I prefer controllers for rpgs like skyrim.
So basically.. you are a prime example of the common misconceptions people have with PCs.
I have a 52" plasma TV and an xbox360. I would have had to spend upwards of $600 to play Skyrim on my PC (new video card, more ram, and a new power source because my power source fan is broken), and I have a tiny monitor and an uncomfortable computer chair/desk.
Was a simple choice. I know I could have gotten more out of Skyrim with mods, but it would have cost me a lot of money. I'd rather play on a PC, but it just isn't a realistic option for me. I couldn't justify spending that kind of cash because I really don't play many games.
Think of it this way. PCs aren't used just for gaming.
PCs are also cheaper in the long run ( Upgrading every year or two is total BS. This only applies to hardcoe PC gamers like myself that want to max the settings @ 60+ fps at all times ). Steam sales where you can get tons of awesome games for $1-5, or 50% off is very common.
