iPod problem: fixed. I got a replacement from the Apple Store at the St. Louis Galleria. The Apple Store experience was unusually, unexpectedly pleasant. I may not be ready to turn in my Windows XP laptop, but when it comes to dealing with the public, it’s Jobs over Gates by a landslide.Final exam problems: not fixed. It’s T minus 20 hours for Exam 1, and I’m feeling stressed and stupid.
