Yep! Still waiting for a bluetooth fix for my ar5b195 to work on boot/wake without having to wait around 30 seconds for it to connect. Everything else is working as good as it did in 10.8( apart from issues that are apparent on "real" macs).
Yes! And it was the EASIEST yet! I made my unibeast flash in 10.7.5 Did a clean install to a new 500GB HDD, ran multibeast with user DSDT then used my time machine backup to restore my files and programs. I'm a little sad I have to repurchase ilife and iwork from the app store because it didn't recognize my install from the previous build but a small price to pay and I got the new OS for free !
