Hmm. My red PRS-600 just crashed for the first time tonight. Legitimately scary. Was out for about thirty minutes, and now it seems OK. Hit the reset a bunch, tried hitting the power button a lot. Didn't seem to do anything.
I did try to connect via USB. It showed the USB screen, though it did not connect to my computer. When I disconnected, it went to the home screen, but otherwise it was still in the same problematic state. Nothing could get me back to reading, or to any kind of change in state.
It was only after I tried connecting via USB that I noticed the LED at the top near the power switch was blinking orange. Not sure what this means, or if it was blinking orange before I tried the USB connection. Finally, for whatever reason it just came back to life: rebooting with the initial splash screen (not the home screen), and it seems to be working just fine now. I did hit the reset button again around the time it came back to life, though I'm not convinced this is what did it.
Anyone else have a similar experience?
