So I just took delivery of my new 24" iMac - typing this post on it as a matter of fact. Everything looked fine with the screen, but I'm hardly the most discerning in terms of gradient - but then I noticed a rather large (well, probably pixel-sized) dark spot just under the default location of the "Macintosh HD" icon on the desktop. Dead pixel, I thought. Wrong, because it parallaxes against the LCD screen when you move from side-to-side, so it's apparently a piece of dirt on the under side of the glass. It seems like it may have appeared during setup, because I had a good look at the screen when all the white was up during setup and didn't notice until I'd been working on the desktop. I'd post a pic if I weren't so OS X illiterate that I couldn't figure out how to get an individual picture of of my "Photo Library" and attach it. Is this the sort of thing I'd call Apple about or go to the Genius Bar? I've never dealt with either one for any of my iPods, which I've never had issues with, so actually getting support from Apple is kind of new, lol! I ordered it at the online Apple store if that makes any difference. I'm really just trying to decide how annoying it is. It wouldn't be too bad if it were on the left hand side of the screen, but it's on the side where everything is placed by default, making it pretty annoying. Ugh.
