This promotional video, released by Microsoft earlier this week, is simply called "Productivity Future Vision 2011". It's the latest in a long-running series the company comes up with on an annual basis, imagining what the world of tomorrow will look like based on advances from the world of today.
God I love this stuff. Real, honest-to-goodness futurism. Something that eschews flying cars and robot helpers in favour of predicting stuff that may be more practical/boring, but which is also far more likely.
About the only downside is there's no input from the Xbox team. Which, given how clean and safe everything looks, is probably for the best.
