Perhaps my comment was rude, and 'a bit over the top' as you say. Microsoft's VP of Operating Systems is probably not a moron.
My initial reaction to Belfiore seeming to downgrade a previous version of their flagship product by referring to it as a first gen Prius, and then extending the bad car analogy to try and sell us the new shiny pissed me off.
Comparing a previous version to an niche, ugly, low powered econobox (that is heavily government subsidized) to an electric car, made by an independent company and is decidedly not meant to be mass market cheap, nor aimed at the same demographic... Having the people in charge of these products make these statements gives me the impression the same brain trust that turned Windows 7 into Windows 8 is still running the show.
What car would he have made Windows 8 in that analogy?
