i can think of a benefit to console gaming, simplicity, every time i've ever played a game on PC i've had to tweak the settings, go through the installation process (which sometimes does not work for older titles) and hope to god it works.
the details for buying a new computer are endlessly complex same thing with graphics cards and if i play a game with incredibly toned down settings it's rendered unplayable not just through graphics but lag and frame rate.
plus all of my computers are pretty much piss poor, because i'm not at all well off with money. i work minimum wage and my parents don't have much in the way of disposable income, they bought me an xbox and a ps3 only because they were on sale at the time and i didn't already have either of them, but with computers if they were on sale i would'nt even know which computer to buy because of all the complicated details like graphical quality and processing power
and don't tell me my computer can handle it if i tone the setting down, no it fucking can't, i toned the graphics down COMEPLETELY for the free copy of Mass Effect 2 i got through some deal bioware had, and not only did it not work, it didn't even start, the game crashed before it made it to the main menu
with consoles you buy it and you know what it does, it plays games, you put a game in there and it WILL work, because that is specifically what the console was designed to do, there isn't a single chance it won't because all games created for it were designed with it's limitations in mind
