Have you noticed that, when the backlight is on (either of the two brightnesses), there is a high-pitch whine/hum? (when the room is very quiet) I am 34 and can hear it. As soon as I turn the backlight off, the sound disappears. Very annoying.

One of the best keyboards I've ever used was a membrane keyboard... Microsoft Sidewinder X4 - remember, it's user preference, the performance between keyboards can be very minimal
