You didn't see the site 18 months ago - went live in May 2011. Release date has never been pushed back - it's always been Q4 2011.
I've got a prototype - works very well, so not vapourware at all.
Where can I get a prototype?
You can't. They are all out with developers and distro people. You'll just have to wait until Nov/Dec.
What the world *really* needs is a good Automatic Bicycle Sharpener.
