I'll probably throw it on one of my virtual machines, just to see how it works but I don't think I'll be using it for anything.
I'm interested... I would give it a shot. I use a lot of google products anyway, so more integration would be nice.
Except MS used a dominant position to get people to use sub products. Google has a lot of smaller products, and is tying them together in an OS. It's very different IMO.
Also Intel said today they've been working with Google for some time on elements of the project.
