When I first started using a computer, my keyboard was black on white. When my Vickie gave me her old computer, the keyboard was white on black. It took me some getting used to to see the keys. I can't type without looking at the keys. There's a new keyboard being advertised on t.v. that seems to be an improvement. The keys are black on yellow and the letters, punctuation, and symbols are larger. There's even a version that glows in the dark. I'm seriously thinking about getting one since the lighting set-up on my computer desk is not the best. Have you seen the ads? What do you think about them?
