My new 20" ACD has a black dot in its otherwise perfect aluminum frame, which is visible from about 30 cm distance. I called Apple and they basically told me it's normal.
It doesn't really bother me, but I'm a bit curious how often this happens.
I'm sorry, I can't help it. Dude, we're perfectionists here, that's why we love Apple (wink wink). But, I think it might be time for a girlfriend... or at very least a hobby.
