52 minutes on the phone with some guy in Pakistan that I couldn't understand just to get an install disk for a machine that crashed 3 DAYS after the warranty expired. Still didn't get it. After 52 minutes, he said "another 20 minutes to wait for system to finish updating".  Thanks Dell, I didn't need that hour of air time for NOTHING. Beyond p.o.'d.
