We all used to love Mac, we all see that Apple has lost its way and seems to be heading more and more confidently in the wrong direction, and that may be just the push the community needs to actually build something.
And what an amazing achievement it would be--an actually open alternative that runs on lots of (powerful) hardware with the beauty of Mac OS (before Lion lol).
I really think it's going to happen because I think a very large percentage of the community now realizes that there is no existing private company heading in the right direction. So we now have to take the steering of the ship into our own hands.
Abracadabra.
