I purchased the 2.26 13" MBP (4GB RAM) yesterday afternoon. When I came home, I set it up and started to notice a couple of streaks (.5" thick) on the right side and half of the bottom of the screen. I have a 9C9E screen and have it tested it on the Earth (centered) wallpaper with full brightness. It tends to go away after 40% brightness. Sorry for the bad picture. Anyone else having this issue?
