Kinda?

So like, if you were upgrading an older system, or buying a cheaper new system: yes.
Driver support sucked, the system requirements were SKY FUCKING HIGH for 2006, almost no one was ready for Aero (looked great if you could run it, at least -- I still think Vista's Aero interface looks better than 7's).
Lots of software incompatibility, too. One that affected me at the time was that every single Game Maker 6 game didn't work on Vista without getting patched, and you couldn't reasonably use GM6 on Vista since while the editor would work, it would generate binaries that wouldn't run -- the author used the opportunity to put stronger DRM in Game Maker 7 and discourage use of the widely pirated Game Maker 6.

I had a buddy who upgraded to Vista. Absolutely terrible. Every single bad thing I'd ever heard about the OS, his machine exhibited. Cosmically bad.

HOWEVER:
I bought a laptop with Vista. 2GB RAM, some kind of dual core Intel thing, maybe like 120GB of disk. I think this was sometime in 2008 or early 2009? Probably 08, since Vista SP1 wasn't out. Maybe they'd patched the worst of the issues out at that point, or maybe I was just very lucky being on well supported hardware that was high-spec enough (if not actually that powerful) to not choke to death.
Worked pretty much flawlessly. Didn't update to SP1 for a while, either.
I didn't upgrade until deeeep into Windows 7's lifespan, and the only reason I did was because one day Vista just didn't boot and I couldn't get the startup repair thing to work. Downloaded a Windows 7 ISO and that was that.
