I had to leave my poor computer there for the day and it was crazy busy in the store. So much so that when my computer was called up - nothing happened so I had to track down someone else and have them go back to find it.
At first the guy at the genius bar thought it was a software glitch but I got a new hard drive instead.
After getting it home (I even had to valet park my car), I restored from Time Machine and I'm back up and running again.
