Personally I use Windows XP Pro with SP2, and I keep it updated ( with the critical updates ). Win 98 was built alot on the DOS System, and Windows.. WinMe - Well it sucked straight out from the box. Win2000, It is a Awesome and Stable OS, especially for Networking Businesses, and was mainly built for such, although some home owners use it.. WinXP Home is a good OS, and Not so many crashes since XP compared to the Win 98 Family of OS's, and without the overwhelming DOS System, and XP Pro was designed or intended for businesses, but alot of private users use it everyday, Pro has a few features that Home does not, and I personally like Pro, and may not upgrade to Vista until I buy a new computer with it.... Like the old saying " Do Not Fix it, If it is not Broken"...... Good Luck
