Sarasota,
I just installed XP about two weeks ago; I upgraded from Windows ME. So far, I am really pleased with it. It seems to be running alot smoother, and it is opening windows faster.
I did have a problem installing it, because I had to download upgrade drivers for my sound card, video card, and printer. Everything worked ok except the video driver. This problem was resolved with the help of a technician from Microsoft, who called me back after I left a message and spent nearly two hours on the phone with me, and they were paying for the call. I finally resolved the problem by downloading the Windows 2000/XP driver for the video card from the Navidia web site. The only thing I do not like is that there is no free upgrade for norton antivirus. It cost about $25 bucks for the upgrade.
Hope this helps.
