Nobody ever blogs about good customer support.
So I sent my Powerbook into Apple to be fixed on Thursday. On Saturday, I checked the repair info page, and the issue was marked as closed. This was somewhat worrisome; I had visions of my poor little laptop lost in Apple’s vast cavernous shipping bays, never to be seen again. So I called customer service.
Turned out they’d fixed it the same day it got there, and dropped it back into the mail. I got it back Monday. Three business day turnaround! Go, Apple.
