Its almost like he needs some sort of disposable covers. Someone needs to invent an optically-perfect, 98% transmissive screen protector that comes in a pad of 100 - when it gets dirty you can just rip one off like a sheet of paper, toss it in the trash (or biohazard bin, as the case may be), and your rolling again
without missing a beat. I am thinking I might need to patent this. There is sure to be profits considering all of the Adams out there.
