Just in case the recent media hype about Windows Vista has confused you, back in 2004, Allchin wrote: "LH is a pig". LH stands for Longhorn. Longhorn was the codename for Windows Vista. Ergo, Windows Vista was a pig back in 2004. And it still is - despite Allchin's attempt at revisionism.
Here's what Allchin - ostensibly in charge of Vista - wrote during it's development:
I think our teams lost sight of what bug-free means, what resilience means, what full scenarios mean, what security means, what performance means, how important current applications are, and really understanding what the most important problems [our] customers face are. I see lots of random features...
Just remember that when you go to upgrade. The guy in charge thought it was crap.
