Hello Lars, I haven't checked my D60s for this problem (maybe I should) but it has been a fairly hot topic over at dpreview.com. It seems like I remember seeing some sort of threshold amount of hot pixels (that is what the error pixels are called) that qualifies for warranty repair. Look in the canon slr forum for more info. Do a search on D60 and hot pixel.
