I thought others might be in a similar situation as me and want to read something positive. I bought the SL yesterday and then came to MR to see how people were faring. Not too well it seemed and so I did a full superduper backup and was considering to wait with the upgrade until Apple released an update to deal with all the problems people were having. But then I went ahead anyway... so much for my willpower. I decided to upgrade and not do a clean install. It took about 50 minutes or so, the first boot up was slow, but once it loaded everything worked and all the preferences were the same, including an activated firewall, icons, dock, geektool, growl, everything just as I left it. I knew CS2 wasn't supported so I left the install CD in the drive, clicked to open PS and it asked if I wanted to install Rosetta to load CS2, took all of a 30seconds and CS2 is running flawlessly. Everything seems to be a tad faster and I had no problems. Just waiting for iStat to release v2 and I'll be all set.
