We have 3 computers, 3 versions of Windows. The laptop is XP Prof. mine is XP Home, and Tom's is 98 second. I do like XP better, it has some really easy to use features that 98 doesn't have. His computer it too old and slow to put XP on. But 98 runs great on it. And it doesn't seem too slow. It came with 95 and we upgraded to 98 second and put in a bigger hard drive. I say 'we', but 'we' have no idea how to do those things, our friend did it for us. I don't see any difference between Prof. and Home on XP. It will be harder to get support on 98 second from MS.And I don't think there is any support now for 95. They just want our money , always newer, better and improved...
