Re: If you have Windows XP, why do you use linux?
Personally, I'm amazed at how fast Windows XP can run when you don't install anything. I keep a Windows XP partition around for gaming. I do everything else on Linux. Write novels, develop software, put together business proposals, remote-administration of Windows 2003 servers... you name it.
There were some things I used to do in Windows that I could not do in Linux. These were 'want' things, though, rather than 'need' things. And eventually I found Linux had so many advantages that I stopped booting into Windows to do Windows things. I just stayed in Linux doing Linux things instead.
(At work I do a lot of server admin work. I switched from Windows to Linux, without telling anyone, and the boss didn't notice for a month! Linux plays nicely with other systems...)
I have nothing, absolutely nothing, installed on Windows XP that is not an integral system component or a game. (Or Nvidia drivers) No anti-virus, no internet access. No extranuous codecs, DVD-rippers or P2P software. Not even winamp. No printer drivers. No Microsoft Office. Nothing. I've turned off most of my Windows services, too. Just one straight-through network cable connected to my girlfriend's machine, so we can play Dawn of War together. (She likes Predator tanks best of all...)
It boots in about 10 seconds, and rips through anything I throw at it.
I am glad it is inconvinient to reboot to play games. It separates work and play to a much greater extent. NOT being able to just double-dlick something and start up a game while I'm working keeps me focused on the task at hand. (Which, right now, is posting on forums.)
That being said, I would not pay money for Windows just to play games. If there comes a time when PC games no longer run under Windows XP, I'd just buy a Playstation 3 or something.
Insanity is all in the mind...
