Anyone else get one with this issue? I spotted it as soon as the Macbook booted up for the first time--it's very obvious on grey or white images. At first I thought it was just something on the screen, but it's definitely a dust speck under the glass. Not a dead pixel either, as you can tell that it arcs at an angle between several pixels. Just curious if I'm unique in my issue here. I've got an appt at the Genius Bar this evening, so we'll see how it goes. Other than this though, the Macbook is perfect.
