When my BTO MBA arrived, the first thing I did upon taking it out of the box was a quick defect check around the body of the thing to make sure there wasn't any major defects I should send it back for. I quickly noticed one on the bottom of my machine. It's almost like a scratch, but upon 'playing with it' I realized that it's essentially remnants from a long sticker. [Although I'm sure that's not what it truly is.] It's almost as if someone took a very small amount of glue and lightly glided it across the back. Does anyone know a good way for me to get this off safely and easily? Also, has anyone else had this problem?
