I suspect that machine spec has a big impact, with the amount of RAM and the choice of video card being the largest variables. In particular, I suspect that there is a bigger difference in relative performance between XP and 7 on machines with only 1 GB of RAM than there is on identical machines with 2+ GB of RAM. For that matter, I bet that there is a significant difference in Win7 performance on machines with 2 GB vs 4 GB.
I do have an old machine that is pretty much at the minimum spec for Win7. It runs XP SP3 very nicely. If I have the time, perhaps I'll try installing Win7 on it for comparison, but I'm inclined to keep it on XP.
I'm looking at Win7 upgrades this way: for machines already running XP, I'm inclined to keep them on XP, but for machines running Vista, it's a no-brainer to move to Win7.
The one thing that might make me move from XP to Win7 on my home machine is some of the under-the-hood security enhancements on Win7, though I haven't examined the issue closely yet. I haven't really talked about this yet, but I've been running an XP machine at home without live antivirus/malware protection, and the performance improvement has been astonishing. Win7's implementation of a "Least-privilege User Account" seems more sophisticated than XP "standard" user, so that might be worth the upgrade.
As an aside, I'm sure that under most circumstances, the performance difference between a machine running antivirus software and one not running antivirus software is much greater than the difference between XP and Win7. Note: I am not suggesting that you go without antivirus protection on a laptop that you use in a public place. I'd only risk it if the machine is on a pretty secure network, and it is certain that the machine will not be used to visit shady websites.
