If you need a backlit keyboard it means that you (1.) are working in an environment that's way to dimly lit to be healthy and (2.) really need to learn touch typing.
Do you have better ones?
(Positioning your hands by sight may not be that uncommon among people who learned to type before the F and J markers became commonplace on computers. I was in my late teens before I first encountered them, and I had to have their purpose explained to me.)
