Upgrading to Leopard
This weekend I spent the time to update my machines to Mac OS X 10.5.1 - Leopard. The updates went well - both PPC and Intel, and while there were a few issues, there wasn't anything that seemed to be systemic about the problems. After the install, I immediately updated to 10.5.1 and that went well. I had to update a few applications after the long install, but those went smoothly as well.
Spaces is nice, it's not the hot-key combination that I'd like, but I can live with it. It's only going to take a little time to get used to the different key combinations. The UI is nice. It's different from Tiger, but there's nothing really horribly wrong with it, either.
There is going to be a time when some applications are not performing 100%, but that happened with Tiger (10.4) and it'll only take a little while to get them sorted out. All-in-all, it was a lot of work for five machines, but it was worth it.
UPDATE: I needed to reconfigure ssh in launchd on sherman (my G5 iMac) to make sure that it answers to port 2224 as well as 22. This is because I'm using that port to redirect it through my router.
