But, I do know that the Jetbook does NOT have a back light. I have used one and can tell you that with 100% certainty. I'm not sure it is an issue of you not understanding this rather it seems an issue of you not believing be.

If the dictionaries are backlit then they have a transmissive screen with a backlight. The jetbook has a reflexive TFT screen. Have you not seen LCD clocks? Most of them are NOT back lit and use a reflexive type screen.
