I bought a brand new 13" macbook pro about 3 weeks ago. However a few days ago I've noticed tiny little scratches dotted all about the screen and i have found more today. Ive been very careful with it so I'm confused where they're coming from..Im wondering if its the keyboard as I've heard this before? Its just disappointing spending so much on a product and for it to have scratches on it so soon when its not like I've knocked it or the metal part of the charger has hit the screen when I've removed it for example :/ I've tried cleaning the screen properly but the scratches are quite deep. Any ideas to the cause of this? Would it be a bad thing to continuously leave the mac lid up even if switched off, just incase it is the keyboard causing these little scratches to the screen? Thanks.
