I've used Windows pretty much all my life, but started out with Linux (Ubuntu, briefly openSUSe and back to Ubuntu again) a couple of months back.

I don't see many problems with Windows apart from it doesn't like moving User documents/data to another drive. The resulting clutter from that is all down to me though. I haven't had an complaints with Vista.

I'm warming more to Ubuntu now (although I only use it as a development platform on a laptop, I'd probably prefer it even more on the desktop) but I really don't see the "horrors" in Windows.
