This poll is incomplete. No mention of Unix, Linux, BSD, or any of the other operating systems out there. BeOS also comes to mind, too bad it's out of business.
I use Win98, and it sucks hard. But, I refuse to pay out any more money to Microslop for another operating system. I suppose I could use Linux, I have tried Mandrake, but it's just a bit beyond my level of comfort. I'm a computer veteran, but not a computer master. Win98 sucks, but it takes no brains to operate it. If Linux were more user friendly, I might take the plunge.
