It's time for this annual thread! What are the first four digits of your serial number, and how is the quality/uniformity of your screen? Mine are DLXN, and the screen is pretty nice - great, even backlighting, great tone and color, but just a wee hint of book spine shadow (dark band from top to bottom on very left edge of device). However I swear that after several hours of use, the book spine shadow has faded a lot and is nearly gone? I don't think I'm just used to it either, as I was toggling back and forth with my iPad 4. Plus I hopped on it when I got up this morning and it looked pretty good with fresh eyes. Leaning towards keeping it, because it's pretty minimal and like I said I think it has faded to being almost non-existent?
