     1.  Wireless keyboards have been tried.  Remember the PC Jr?  Not
	 only was the keyboard wireless, it was washable.  Didn't sell.
	 Keeping multiple machines in the same room from interfering
	 required a more elaborate communications approach than the PC Jr.
	 used; this limited applications of the machine.

     2.  Large, flat plasma panels have been tried.  IBM used to offer one
	 as a mainframe peripheral, and it's even been seen on a PC at
	 Comdex ('84).  About 2 feet square, and red.  The interface had
	 some problems that made it very painful to program, but the device
	 worked quite well.  Plasma panels about 6' x 8' by 4" thick are
	 available for about $100,000, but these are militarized units.
