Hehe... okay, maybe stupid is a little strong

- "uninformed" maybe...
Firefox really has plugged *the* hole in Windows XP - I haven't had a single incident of a worm, trojan, even web-popup, since installing it... and in my experience using Linux at work - maybe Linux itself is rock solid, but the software written for it crashes ten to the dozen (even the Linux version of Firefox!) - and it crashes far more than my Windows machine - the only very occasional crash I ever get in XP is due to a graphics card glitch (most likely overheating - I have got it overclocked)
I certainly don't write off Macs - they're pointing the way forward in a number of ways, and they are great for multimedia production purposes, video editing, etc... But they are *not* games machines, and they are *not* raw performance machines either...
Sure, "Most of the AAA titles come to Mac" - and yes, "AAA" titles rule the console market too... and its exactly that reason that I have zero interest in getting a PS3 or a 360... samey shite all the way.
If you actually want innovation, variation, and the widest possible selection of games from all genres, the PC is the way to go... - Its getting overshadowed by the *next* street-racing game, and the *next* Halo clone, and the *next* 3rd person action game, but all those come out on PC too... so you get a pick of the lot, and for a machine twice the power of a Mac, for half the price!
Macs are very much about visual appeal, gimmicks, something you can flash around and show your mates, or give your swanky office a sleek professional appearance to impress the clients - our company only buys macs for the editing suite, because thats where the clients spend most time - the ones we actually work on are all dual-xeon PCs... we use Quicktime across the network, on all the PCs, we have colour management integrated... it not all exclusive to the Mac - they just try and make it sound that way.
To sum up, all systems have their advantages... and the old "Windows crashes every 10 minutes" argument just doesn't hold any more, XP is up there with Linux and OSX provided you write Internet Explorer out of the equation. Whatever benefits macs may have over another system, it is undeniable that you pay an absolute premium for a very well marketed machine, with limited software and hardware versatility.
