So far Windows 7 wins hands down, yes I have some compatibility issues with Vista and Win7 but I also had issues with XP back in the day. Example is the vpn software we use, the developers are always slow on an upgrade. So I just VMware my old XP and use it like and application, I know in time the develpoers will get the software ready and I will have the vpn back as a service on the host os.
I like XP, Vista and Windows 7 (as Bobby)
