well, my friend had that a month ago, and after a while, the entire R button and the indicator light cover just broke off. He didn't abuse it or any thing, so i guess his was just faulty.......
or so i thought
yesterday, i woke up, got ready for school, and started packing my ds up, when i saw that there was a crack, right where the power switch was. It was only in the plastic lineing, but it had started to pop of (the plastic lineing i mean). This made absolutly no sense, seeing as i carry my ds in the original bubble wrap type thing, plus a case, everywhere i go (yea, call me crazy, but i like my ds shiny when i play it) so, i brought i to school, thinking "yea, if it gets any worse, ill just send it back" seeing as i was too stupid to get a extended warrenty last time. So, at the end of the day, were on the bus, enjoy a game of Metroid, when the R button stops working! My friend (who i talked about above) said it was basicly the same thing that happen to him, R button and all, so when i got home, i grabbed some games, some cash, and headed to my local EB. This had been the last straw with my white lite, so i got my self a black one. I had decided that 3 weeks was too long for me to wait for a new ds, and that black was nicer. So to answer your question yes, there is such a thing as the fracture. Sorry about the long post, i just had to get that off my chest.
