thats probably not the idea you wanna hear, but if you learn touch typing you dont need to read the letters off of the keys
aside from that, the Eclipse and Eclipse II are both illuminated, the Fatal1ty edition keyboard from Creative Labs is illuminated, Logitech has the G11 and G15 keyboards which have illuminated characters as well
theres also a number of cheap no-name illuminated keyboards available at various places on the internet, although touch typing is probably going to be the better option, given that it would likely save you money and increase typing speed.
because turning on lights in my tiny apartment during my odd, free-lance working hours disturbs my partner.
for the same reason.
because I'm a 2-finger typist and so am hard on hardware.
I am currently disappointed in the Saitek Eclipse--the letters on the most-used keys (e, r, t, i, o, a,s,d,c,n,h,) smeared into illegible blue blobs after only three months!
