Well good for you. Your eyes are better than mine.
You can always turn the backlight off.
I didn't connect the two statements directly, but I can see how it came across that way.
My point is that it's better to have and not need than to need and not have.
I like not having to rely on ambient lighting to see the keys. The backlight makes key visibility a complete non-issue for everyone.
But hey, to each their own.
I DO turn it off
