Just noticed yesterday when booting a bright spot about a couple of mm and round near the bottom left. The machine is a few months old. I'm disappointed in the quality of this air display in general. The light along the bottom is not even, and now this defect. I've got an appointment to see a genius today in my local mall. I really don't have time to be without this machine for that long, but I thought if I wait my chances of getting resolution might be compromised. Will post back to let you know what they say. I love this machine, but this bad screen issue is really not boding well. I've been pretty careful transporting it, but I'm thinking that I might need to get a more seriously protective bag for it, which defeats the purpose of having such a small, light machine. It's amazing how sick you feel when something you are so attached to isn't perfect. It makes me want to just buy a cheap pc and not worry about having the best and latest.
