You don't have a choice for my Kindle crash/reboot experience in your poll.
My Kindle WiFi has only had one spontaneous reset since I received it; I received it on October 8th. The page turn button suddenly wouldn't work when I pressed it and then the unit rebooted on its own. No problem before or since then. My Kindle came with firmware version 3.0.1 when I received it and it had version 3.0.2 on it at the time of the spontaneous reboot. It is currently running on firmware version 3.0.2.
