I dont know why people are so out to hate on Microsoft. For how big of an endeavor creating an OS that can run well on the myriad of different PC configurations is they do a pretty good job.No.... Windows will not be F'd in the A. I work in IT and this is one thing I know.
Linux only has a small small percentage on the server market. Desktop... they don't even show up as a blip on the radar.
I work in IT as well, and while I have my gripes I think XP Pro is a nice OS, and it definitely keeps improving with each release.
