Hopefully after this the machine is saved from scratches, but not from fingerprints and heavy usage of the keyboard. After two years use, the painting is almost gone on mine from the A, S, E and cursor keys.
Better get a stand (like the Griffin iCurve) and use an external keyboard and mouse.
I have to admit that there are too much Radtech ads here, but the products itself (even if they are just too basic) rock. Hey, Radtech, you care about donating some?:)
