There was certainly a distinct lack of babies in Vista
Eh, honestly, I'm not all that impressed with that video either. I dislike the gimmicky, memory-eating, and let's not forget practically useless clutter that they keep trying to stuff into Windows. For me, actual improvements to Windows ergonomics since 95 have been numbered in single digits, for all the millions that they seem to spend on it. Considering there's hundreds of ways you can change and customize your Windows shell without having to buy a new OS, I think all this kind of development is a huge waste. The effort would be better-spent giving us features we actually need. Like a more efficient file system and such.
I don't mind Vista though, but for all the money and effort spent on it, they ought to be ashamed. There's still not a single reason I'd prefer it to XP, and at least one reason I'd prefer XP over it (memory consumption). I still have it on my laptop though and I don't plan to get rid of it. For all practical purposes it works just fine.
