I just bought a 2011 MBP 17" to replace my 17" Unibody C2D, what I noticed are the keys... the seem to have a different coating on them that makes staining them with the fingers a lot harder.... I have no greasy fingers at all and wash my hands constantly and after a few strokes my keys in my old mbp would look a bit glossy in places... I just noticed this does not happen with the new mbp... you guys noticing this or am I hallucinating??? lol
