Had a phone start freaking out on me two weeks after I bought it, and honestly expected to be given the runaround about the warranty. I scheduled an appointment at the Genius Bar and showed up to a packed house. Around me were many tales of woe leading to Genius Bar appointments on a Saturday night, but everyone was seen and addressed fairly quickly.
I heard patience with the less technically astute in the crowd, and was seen within 10 minutes of my appointment time. The guy saw I knew what I was talking about so he pulled the diagnostic, saw what I suspected, and gave me a new phone on the spot. I was up and running in 10 minutes.
While I wish it was under better circumstances, and that I'd had a fully functional phone/camera while camping, I've got to hand it to Apple. This experience didn't suck.
