The most common style of computer laptop has a keyboard
portion which sit's on a table (or one's lap), and a screen
which sticks upward from a hinge on the back of the
keyboard.
I propose a laptop which has a screen section which sits
flat on the table (or one's lap) and two half-keyboards
attached to it on the left and right sides.
The attachments would either be via two hinges, one on
each side of the screen (like the screen-keyboard hinge on
a regular laptop) or using some sort of ball and socket
joint, to allow the screen to be tilted upwards.
The keyboard sections would, in effect, be the two halves
of an ergonomic keyboard.
The CPU would probably be behind the screen, and
peripherals (CD drive, SD Cards, etc) would be inside the
keyboard halves.
Obviously, the screen would need to be designed to be
viewed from a significant angle.
