I've been running Windows 7 on my laptop since it was released and really like it so far. Never ran Vista as my primary OS but did have it installed on a dedicated gaming desktop for a short period of time. Don't recall having that many issues with it like others have reported but maybe I didn't run it long enough to see them. When I compare Windows XP Professional to Windows 7 I guess I'd have to say I prefer Windows 7 but can't really put my finger on any reason/reasons that would cause me to spend the money to upgrade. If getting a new computer any time soon I'll wait till Windows 7 is release but I see no reason to go get retail copies off the store shelves to upgrade the four user computers I maintain in my house. Guess there is no real reason to upgrade them all if I'm the only one that cares but from a support stand point I really like having all my user machines running the same OS. As this forum is for Windows users I figured it would be a good question to ask here. What am I missing that are causing people to pay retail prices for these upgrades. Windows XP Professional is doing great for me. Can't see a reason to spend the money. Asked this same question on the official Microsoft forums for Windows 7 and it got completely removed as far as I can tell.
