My work board is non-backlit, but my home board is backlit. What I tend to use it for is to confirm keypresses (backlight only lights up when keys are pressed), as all my password entries are complex and in the bash style, which means I have no clue how many characters i put in, so I can't really guesstimate where I went wrong. So if I type a password wrong, I'll know because of the key brightness (10 ticks) compared to what brightness it should be at the point where i finish typing a password. So, for example, my password is "Hunter2" by the time I've inputted the password completely, the H is at brightness 2, the shift key is at brightness 2, the U key is at brightness 3,the n key at brightness 4, the t key at brightness 5, the e key at brightness 6, the r key at brightness 7, and the 2 key at brightness 9. Otherwise, my backlight is off.
