Wii Warm Up: Technical difficulties

Since the release of the Wii, we've gotten a few e-mails from people reporting that they've had various problems with their systems -- and we're not talking straps here, but actual technical difficulties. In light of that, we figured it was a good time to open the floor to everyone and ask: have you had any issues with your Wii? Controllers not working, discs not reading, tears, recriminations, explosions ... any problems at all? If so, we want to hear about it.
