Over here PCs represent the de facto standard for gaming. Consoles are cheaper in the short term, but people have come to realise that in the long term a decent PC is much better value for money than a PS2/GameCube/XBox. Not only are PC games far cheaper (here you’ll easily pay two to three times as much for a just released console game as opposed to the same game on PC), but as a rule PC games offer far more depth and a far greater variety of choices.
And sure, some people will complain about the cost of (Microsoft) productivity software, but seriously, if you don’t mind searching a bit you’ll find a free (usually released under the open source banner) version of whatever type of program you need.
In conclusion, as long as there are intelligent gamers, there will be a need for intelligent games. And those you usually don’t find on the consoles.
