Apparently it IS possible to damage the Wii Remote. To be clear, I've been very impressed with the Wii Remote's durability. I've seen it tossed through TV sets, glassware, and all the usual things listed on the panel to the right. Usually it comes out with nothing more than a rattled battery back cover. Frankly I think a rattled battery pack cover is right of passage for any sort of remote. It's like a hockey player losing some teeth. Oh sure they say they play hockey, but do you really believe them if they still have all their teeth?
Shawn from down Georgia way explained how a mucho macho game of fast pitch led to a broken B-button...
"we were getting our friends together to play wii sports baseball, when one of them claimed to have pitched a 95mph fastball. the next day, he tried to pitch it at the same speed. moments later the wii remote crashes to the floor, with the strap still around his wrist. the remote does not work anymore. the b button is cracked down the center and can hear a rattling sound when the remote is shaken. i dont think he ever pitched 95mph, and probably never will, at least on my wii."
Apparently Shawn also threw his keyboard breaking the Shift and Capslock keys, along with anything else that would cause proper capitalization in an email. At anyrate, a 95mph swing into the table will crack your B-button. I want you to keep that fresh in your minds when you play children. Fresh like strawberrys grown by a Rocky Mountain stream.
