I don't think either Wave nor Vista were poor quality products, same way I don't think Glass nor Phone were poor products. The engineering on all of these is fine for the most part. Sure, there are bugs, but not really any more than usual. The real problem is that nobody really wanted these products in the first place.

For Wave, most users didn't seem to figure out what Wave was actually useful for (and it didn't help that Google wasn't sure either). For Vista, people liked XP and dragging them kicking and screaming into a software upgrade turned out to be really hard. Vista set the architectural foundation for future Windows releases, and Microsoft had an obligation to take people off of what was then a 5-year-old operating system - much like OS X 10.0 attempted to do. Nobody seems to pay much attention to the fact that 10.0 was incredibly buggy and took quite some time to bring up to a usable state.
