So I'm used to looking at my iPad through a thick, protective layer of smudges, fingerprints, grime, coffee droplets, and all manner of yuck from my big greasy paws. Occasionally I clean it. But just a little big ago I reached out via habit and TOUCHED THE SCREEN OF MY NEW MacBook! My precious has a smudge! It's like the first scratch on a new car. I can't stand it! So that made me think, what do people generally use for cleaning MacBook retina screens? I assume like any tech screen, gentle is best. I'm thinking maybe just a slightly damp soft cloth? Eyeglass wipes? Dry microfiber cloth?
