I must say, having tested it first hand that it is very ... interesting. I do like the OS itself, it's fluid and the best part is the pulldown settings (view video
here if you don't know what I'm talking about) makes things much faster.
All that being said, it's clearly a very early build. There are a lot of bugs and it's clearly targeted towards developers and geeks like us. It is not ready for use as a daily driver (unless you like that sort of adventure). Also the lacks of apps at the moment really hurts it. I can't live without my basic apps (titanium backup and tasker).
