well..there is one thing really. convenience. that's about it.
on the downside you have vastly weaker tech, overpriced hardware (you can easily assemble a PC for the cost of a console that will outperform it), less flexibility in controls (controllers are good for some games, but playing fps' with two wobbly thumb sticks is a travesty) and generally "simpler" games (which doesn't have to be a bad thing though, if you prefer cod 24 over arma or other more complex games, it's ok), no mods and less backwards compatibility (there is not a single game i have not been able to run on my pc yet. not. a single. one.)
however, i'm not saying console have no place. there is people out there unwilling or unable to learn how to operate a pc, although it's really not that hard to be honest. and for those people, consoles are an option, sure. i, however, are not willing to pay more for a technically inferior system just to avoid reading about the ins and outs of my hobby for an hour or two. that doesn't make the people who rather wouldn't and are willing to make sacrifices for some convenience worse human beings though.
what really grates on my nerves though is the amount of misinformation that some people display.
"you need to fiddle for hours with every game on pc before it runs!"
"a three year old pc can't run modern games anymore!"
"you need to pay 800 bucks for a gaming pc!"
seriously people, at least get your facts straight.
oh, and also, i am by law required to include this picture, if someone else hasn't yet.
