I agree with Ben..... if it ain't broke then why fix it. Why buy a new operating system and have to go through all the hassle of backing up your files and reinstalling ALL your programs?....when what you have already works fine? I did when changing XP to Vista and experienced huge hassles as most of the hardware and software I had was not Vista compatible. I spent weeks trying to find drivers and eventually had to blow it all away and go back to XP......Once bitten comes to mind.
