There probbably won't be any big big failure, but if you want to be sure it doesnt crash, stay with 10.4.10 and wait till 10.5.1 comes out in the next month or so.
Another suggestion: Watch these forums and let others do the initial testing. Might sve you a lot of frustation and time. Maybe a new forum for 10.5 might be an idea.
Good luck, Kees
