Our primary desktop died a few weeks (months) back and I only replaced it last week. I was waiting for Windows 7 to be released. I know there were a lot of companies offering Vista machines with a free upgrade to Win 7 as soon as it was released, but I really didn't want to deal with the hassle of upgrading the OS. Has anyone else made the switch? I never moved to Vista, I kept XP on all my machines so I really don't know what's "new" with this OS from it's predecessor. I've been pretty impressed with it so far, I haven't had any compatibility problems. I even installed MicroStation v7 on it and it runs fine.
