Considering what most folks have to go through to discover them, it's not much of a problem, any more than all the dead bytes or sectors on virtually any new hard drive. They're invisible to you (on the hard drive) because the OS blocks them out and doesn't use them. It seems the same applies to most of you with the dead pixel issue - someone brings it up, then many others start looking, etc., and become dissatisfied. Otherwise, they'd be invisible to most of you.
