Utopia as its often depicted does suck, but the video shown by Microsoft is in no way utopian - it looks like the present, only with more displays (and invisible batteries).

Also, it's 6 minutes of software perfection - I have that sometimes... before Windows throws me an error, my Bluetooth stack fails and disconnects my headphones, my virtual machine hangs up, my phone's browser freezes and I can't close it (damn you Android) and my virtual desktops all meddle with each other since Windows (sigh) can't handle them natively and Dexpot just crashed :-).
