I used the Combo updater. I walked away for my morning coffee while the update was in progress, so I don't know how long it took. The only glitch (and this happened with the 10.4.5 update also) was that the Adobe Bridge icon in the dock was was replaced by a question mark. It was a simple matter to remove the question mark and reinstall the Bridge icon in the dock.
Otherwise, everything seems to be OK.
