The only problem I have had with 10.4.11 (which first appeared with 10.4.10 and persisted with 10.4.11) was the sudden failure of the Superdrive in my G4 iMac. This problem has not been unique to me, as there have been several long threads about it at the iMac Discusssion Forum at Apple Support. Curiously all of these threads have been closed recently by Apple. I reported the Superdrive as a bug to Apple Bug Report. Unlike all previous problems I reported to Apple Bug Report which received some kind of prompt response, I heard nothing back for nearly 2 1/2 months (Nov 1 to Jan 10). I just got an email stating the Apple Engineering would like to investigate this problem further and would I please mail my iMac to Cupertino! As this is my main machine and is working fine other than the SuperDrive, Apple will have to wait awhile. Hopefully, one of the many other sufferers of this Superdrive Failure will send their iMac to Apple.
Ron, is this problem only with iMacs? Or are other machines affected as well? I have a Superdrive in this iBook, and I'd just as soon stick with 10.4.10 if any of these machines might be affected. I don't use Safari much, so unless there's a compelling reason to use use the newer version, I might just stick with what works.
Thanks everyone for your responses; Harv, I'm all about verified backups after the failure of my MDD last winter!

All the complaints about Superdrive failure that I have seen relate just to iMacs.
