Given the popularity of iOS and the growing popularity of OSX, I'd argue that most users disagree. Given the direction of Windows 8 it looks like we're getting more animation in the future, not less, and I for one am happy about that. Animation offers important cues as to the nature of the UI and data you're dealing with (the sliding screens of iOS and Android implies a hierarchy without having to waste time/space spelling it out for you, for example).
In any case, the MSFT video bothered me when I first saw it in a way that I couldn't really place, but after thinking about it some, I think my problem is this:
What is all of this utopian future-tech going to do for, well, regular people? The woman in the video is clearly very wealthy - I mean hell, her hotel has someone just standing around waiting for her cab from the airport. Her (presumable) husband and child live in a home far larger and more luxurious than anything my sorry middle-class ass grew up with. It feels... elitist.
Yeah okay, so jetsetting VPs and rich people have some sweet-ass tech in the future... but where is the technology for the everyman? I'd much rather watch/read about what technology of the future will do for everyone, not just the minted upper-class. Maybe it's just the economy we've had recently, but the video feels slightly repulsive in the fact that their vision of future technology apparently has no middle-class people, or indeed, middle-class concerns.
