Lots.... LOTS!
I have around 40 to 50 xbox games, some I bought on sale but half of them I bought on release date...
But money isn't the only problem though.
With a PC I'd have to learn a lot about what I actually "need" and "how" to upgrade and install it and then find out where to get it.
Then I need to constantly check up if I have the latest functions and make sure I don't mess around with anything so I corrupt it.
Might be a cakewalk for regular PC users but I have very little time for these kinds of things at the moment.
Yeah yeah, "it's my own fault" blah blah blah...
Still... If it's possible to bring some stuff from the PC community over to the console community without using user created mods/patches/japanese schoolgirls, then I say "do it."
Not like it's going to hurt anyone if they do decide to give the console users a wider range of options.
No, once your PC has been put together it pretty much runs itself. You can update drivers often if you want, but runtimes are always included with a game.
PCs aren't some magical boxes you can never understand, they actually can't do anything complex at all - they just do simple things really, really fast. You pretty much can't break a modern OS without knowing what you're doing and giving yourself the neccesary rights to do it. Building a PC is pretty fun, very easy, and will get you a lot more comfortable with your hardware - I know exactly what's in my box, and what each bit is doing. When I hear a noise, I know what's making it, and I probably know why (because let's face it, there are only a few noises it can make), but a console? Not a clue, and if something goes wrong? Off to the manufacturer.
I'd actually go as far as to say that PC gaming is easier than console gaming - I don't have to worry about discs being damaged, I don't have to worry about it overheating or damaging game media, I don't have to worry about losing my saves, or it just /failing/ one day. It's also, over medium-long term, cheaper, more flexible, and gives you a better PC for day-to-day work (You ain't never lived 'till you've used MS office at 10,000fps).
Of course, consoles have a lower initial price of entry and don't require a minimum of research to join. They're also much better for spontaneous local multiplayer, though I argue that LAN parties keep the crown for planned local multiplayer.
Thing is, once you get below a certain level, if you're only using either as a toy, purely to play games... they both play games. Any is a legitimate choice, you just have to figure out which machine's strengths you prefer. And modding is a strength of the PC, where resource scarcity is much less of an issue, so you can add a lot more stuff before you run out of space to put it. So, the short sentence "Want mods? Get a PC." isn't elitist clap-trap, it's just a strength of the PC.
