Installed it; seems to work pretty good. There's some wackiness with Adobe Creative Suite. http://kb2.adobe.com/cps/905/cpsid_90508.html
In general, Adobe is crying foul play at Apple; saying that they yanked hardware support for Flash. They had to retract that statement.
Adobe is full of shit.
Yeah; Lion actually fixed a problem with my new iMac. I had a "reboot" problem; the mac would only boot to it's internal drive. Couldn't get it to boot from an external no matter what I did. Looked online for help, many people said it was a hardware issue and they had to take it to Apple to fix. Installed Lion and burned a backup disc and it booted to the disc! Don't know why it worked, but it did!
