I also didn't say that Microsoft could've done better with Linux. I just said they would've done well.
I also said that Microsoft's time and investment in Vista will probably produce something special. I wasn't being facetious. I actually expect Microsoft to produce something very interesting with their investment. There's a ton of room to grow and innovate.
Well MSFT invested a ton on Longhorn and then scrapped it. Vista is just a different face on NT.
