I read it, and it seems pretty plausible. It matches up with what I hear from friends who've updated.
I, of course, have said for some time that I wouldn't consider Leopard before 10.5.3.
Now I'm thinking 10.5.4.
Apple should have slipped Leopard a solid year, instead of seven months. Beyond the general bugginess I hear off, there's no doubt they made some arrogant, arbitrary and just-plain-dumb UI changes.
The current recommendation has to be:
- Do not install 10.5 on a Tiger machine. Just don't. If you'd like, wait until I do it and say it's safe to proceed. I am very good at finding bad stuff.
- If you can, put off buying new Apple hardware until 10.5.3.
- If you must buy a machine now, don't migrate any apps or settings from old machines. Just move data. Backup rigorously. Install applications carefully and check that they're all Leopard safe.
- Refrain from making rude remarks about Vista.
