WinXP looks like the bastard child of Mac OS X and a Barbie doll.
But I have never had it crash, and it runs MAX with hyperthreading. And can use the drivers for my scanner. And that is all I care about. So HA.
In the end, that's all most anybody's gonna care about. Viruses suck, but most people keep backups. Security just isn't an issue for Joe PC Owner, because since he's got nothing of particular value on his machine he'll only get the most random and hence the weakest of attacks. Windows runs all his peripherals, can use basically all the nice hardware out there today, and it's usually what his computer came with. Sure, fine Linux might be better, but XP does a good enough job for most people that the trouble to install a new OS (with all the inevitable compatibility problems that'd generate with the user's old Windows data, and don't tell me they don't exist at all, that's horse****) is just too much. So, really, going on about how Linux is superior for security and about the same for GUIs comes to naught- all you're really doing is patting yourself on the back for having a very special operating system. Well, good for you. You haven't accomplished anything to speak of.
