Only in Developer Preview 1, but it's solid ... and for me, most importantly, OS X has got it's fluidity back. Launchpad FINALLY opens smoothly and quickly on my iMac and going to/from Full Screen is no longer a slideshow.
Thank you Apple!
Add another vote to the "Installed on external and it seems faster" poll. I don't see a whole bunch of differences between the two OS's and the only reason I am staying with Lion on the main HDD and ML on the external is because I am afraid of the lack of third party support for Mountain Lion at this point. Is this a legitimate fear?
Other than that, I am tempted to make it my main OS. Sure seems smooth for the first preview.
I have your exact same mac specs and experienced the same isssues in Lion. Excited to hear this!
Wow, an OS that [in developer preview] runs BETTER than 10.7.3. What can I say. Oh.... Good job Apple 😀
The animations were my main gripe with Lion, it just removed from the whole experience of using the OS when you had to open/close Launchpad a few times to "get it going" so the animations were acceptable.
Just ran Software Update after reinstalling iLife 11 and Aperture from disc, and it now opens the Mac App Store and updates via there.
