Laptop design
If you put all the circuitry and battery behind the display, then opened the laptop, wouldn't it fall over? Unless the transparent keyboard section is heavier than the rest of the thing, that is, but after all the effort to make the rest of it light, using lead-crystal for the keyboard section sounds like a high price to pay for cool. At the other extreme, a little stand-up leg to come out of the back of the display half would be too un-cool to be balanced by the transparent keyboard.
