My recollection is the XO-4 Touch laptop has the same core LCD screen
technology as XO-1 except for some physical tabs to make it (the very same
1200x900 LCD's originated from Mary Lou Jepsen & All) fit in a bit

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

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
