I have had a DSi for a month now and I noticed a problem once out of the box. The R-button clicks but make no response, only pressing harder then necessary will make a response(with fluctuations in and out). The L-button works wonderfully. This is a horrible thing when playing a game like 'band brother DX' and I have made up my mind that can't live with it. I have taken apart my DSi in hopes to fix, but with no luck. What do you think I should do? Get Nintendo to fix it? Get my hands on a replacement button? What? This thing is driving me mad.
