Running along beautifully. Was dealing with all the latency issues. Have it installed on mac pro 8-core, Macbook Pro 17", iMac, and a Mac Pro 4-core. Last night I was doing some basic graphic work on my laptop when my saves started to take longer and longer. Eventually I got the Beach Ball of death, and decided to reboot. Mind you, it took 15 minutes to get all the running apps to Force Quit, but they did. After a reboot my laptop just sat and spun and spun. Never reached the login page. I pulled out my backup drive, slapped it ink and it booted fine, phew, the CPU and computer itself appeared to be fine. After 6 solid hours of diagnostics, it turns out that Lion literally ate the drive in a cascading sector wipe. For those of you who don't know what that looks like, imagine randomly scratching your grandpa's WAX LP then trying to play it. I'm now VERY worried about the rest of my machines. Is it only a matter of time? My drive had tons of free space, so it wasn't trying to swap blocks etc. It simply died. I reset the PRAM. Tried to reinstall Lion through the recovery, and the drive is so destroyed it can't read the Lion installESD.img that it wrote to disk. Nice. Now I have the joy of calling Adobe and begging them to give me another activation number. Lovely. Beware, Lion ain't ready for primetime. 10.7.2 is probably your best bet. That is if you're a professional using your computers to make money.
