Ok, I'm back on the Mac after a significant hiatus. The time away, I should note, was not because the Genius Bar didn't get the Mac back up and running as promised.
Approximately 8 days after I experienced the Genius Bar I thought to myself, "Dean, I wonder how that Mac is doing..." Then I thought, "Hmm, I wonder why the Genius Bar hasn't called me with the good news..."
So I looked around my house in an effort to find the paper they gave me when I walked out of the Apple store. Yes, I managed to misplace it but mentally backtracking quickly led me to the Applecare box where I had conveniently stowed it. I called the number on the paper, typed in my service number and the friendly computer, which was most decidedly one of the sythesized Mac OS X voices, noted that my iMac was ready to go. Note to self, the Genius Bar lets you check the status of your iMac rather than call you with the news. Not a big deal but good to know.
I picked it up without incident and was delighted to find that everything works quite nicely. I finally broke down and ordered the additional RAM (now at 2 GB) and everything has been humming along very smoothly without any of the issues we experienced before.
I don't have any new photographs as I've been far too busy to take any but I did print this one up to put in my gray cubicle at the office. It seems to add the color and warmth that the neutral colors of my desk scream for:
