Has anyone tried to use the black moshi palmguard on the new aluminum macbooks? My dumb arse, fumble fingered my portable palm drive and it landed square on my palmrest and put a very small ding it in. Its giving my OCD a fit and my eyes just can't seem to stop being drawn to it, so hoping this palmrest would cover it up. Which is why I don't want to use the clear versions. Baring that, does anyone know how much it would cost to replace the top keyboad/palmrest cover area of the unibody?
