I could be wrong, but possibly these new plastics-or-metallic bits allow the screen to bounce better on dropping of the laptop, to reduce screen shattering? Certainly the (multi)touch functionality of XO-4 Touch screens arise from IR (InfraRed) sensors that stand physically above the LCD screen by a few millimeters. -- Unsung Heroes of OLPC, interviewed live @ http://unleashkids.org !
