I may not need light to work, but my keyboard does.

It's probably not a good idea for a woman who doesn't need light to depend on a computer keyboard that requires light to maintain a workable energy level. I work all the time in the dark, never thinking about how I need to turn the light on or open the blinds to allow my wireless keyboard to recharge its battery via solar energy. I bought the keyboard thinking that the solarpowered technology was pretty cool, never considering that this blind woman would not be married to a lit up work area like most sighted folks. Oh, well... I still love my keyboard, even though it's quite unhappy with me these days.
