Got a 13" today and I'm beginning to wish I'd bought an 11". There's an element of backlight unevenness in my lower left-hand corner which is a little annoying when using full screen Safari - though it's liveable with. I also noticed a scratch straight out of the box on the front, under the glowy Apple. Quite annoying. Anyone else in the same boat, for different reasons? Opposite opinions also welcome. Obviously no-one can tell me what's best for me to do, but I wanted to gauge opinion before making a rash return decision. Cheers.
