As mentioned yesterday, I returned to using a PowerBook, the same one let go just a few months ago. One reason the temporary switch was so dumb: Somehow when backing up the contents some error occurred that I missed. The “2005” folder containing all pictures taken this year didn’t copy. So, when wiping the PowerBook’s hard drive, I inadvertently deleted thousands of irreplaceable photos, the majority taken with a Nikon D70. Bummed is too weak a word to describe my reaction.
