I own a Zune30, which along with every other Zune30 decided to "freeze" at exactly 12:00 Midnight PST. By "freeze" I mean it rebooted itself, but got stuck at the Zune boot screen. No series of button presses or screaming at it (as demonstrated above) resulted in getting it past the boot screen. My next thought was "Well, I guess I could just let the battery run out, plug it in and see what happens." That's when the light bulb went on. "Why don't I just disconnect the battery and reset it that way", I thought. Well, after verifying how to take my Zune apart, I proceeded to do exactly that, and voila! -- my Zune is up and running. People have been posting some pretty funny stuff -- someone even went so far as to create a video dedicated to the event.
Here are two more funny images related to the problem.
