I'm looking forward this. A good lightweight Qt DE is more than welcome.

This is exciting. I really hope they keep the components loosely coupled, so that I can easily swap in xmonad and other goodies.

Exactly! I am using xmonad with Unity (well really only using the universal menu bar). But I have to stay < Ubuntu 10.10 for it to be compatible. I get really nice convenience of a modern, stylish-ish interface with the easy navigation of a custom configured xmonad WM. I would love to not be stuck this far behind in the distro's release cycle. Also, I develop with and really like Qt. That is a big plus for me.

Advice for everyone wanting to try Razor and use it on daily basis: Have KDE already installed and then install Razor. This way the functionality that is lacking in Razor will be covered by KDE, in my experience this is the most painless way to do it.

Nice. Wildly extrapolating from this GNOME and KDE should join forces to create one Qt-based desktop; GNOME-Qt. ;-)

Sure, right after iAndroid, Winux and Java#.

c'mon it's a lot more likely than any of those. but can imagine a future in which the only way to run Windows on new hardware is in a Linux VM.

c'mon a future in which the only way to run Linux on new hardware is in a Windows VM is a lot more likely. Just wait for the next 9/11 and Patriot Act 2.0 that makes software non-DRMed by big corps illegal...

GNU/Linux yes, but in that scenario I'd expect to be able to run Android/Linux (FWIW I don't care about the naming argument, just disambiguating here) on new patriotic hardware...

Edit: maybe Windroid is the most likely of any of the wild cases above. :)
