Windows ME is generally regarded as the worst offering ever from MS. But whenever it is discussed online, there are always a few people who would honestly say that they didn't know what the big deal was, it had always worked fine for them. Looking at internet discussions about Vista, I've been noticing a similar pattern. Vista SP1 has apparently fixed some issues, but looking at this thread, it sure is picky about installing. I'm sticking with XP for the foreseeable future.
