Paul, having been a tribologist for BP Oil for years, I think I too can add to the discussion. To prevent stiction, and charging, squirt oil on the screen. As dust accumulates with usage, quality would deteriorate, so one would simply wash the screen, or pop it in the dish-washer: <Having spent four years working on a MEMS based product I think I can add to the discussion. Two issues plague MEMS designs: stiction/welding, and charging. Stiction occurs whenever the MEMS comes into contact and subsequently will not separate. Charging changes the behavior of MEMS to control voltages over time due to various surface charges, usually assumed to be water. > The oil would act as a lubricant and insulator. It would also be good in rainy conditions, so it would be like water off a duck's back. Oil could be stored in the computer and double as a coolant by convection. A little button could be used to activate another little squirt of oil to keep the screen refreshed. Anita [TM] is due for an upgrade. Mqurice
