If you're looking for an inexpensive replacement USB backlit keyboard, I just got one that actually seems pretty decent, replacing a keyboard I bought a few weeks ago that I've not been able to get used to effectively. This latest one is actually my first backlit keyboard, and they've done a decent job at it. I can provide a lot more details if anyone wants. I tend to destroy keyboards quickly whether they're expensive or not, so why buy expensive ones? I've been touch typing since I was a teenager (though at the time I learned I had no idea I'd be spending my entire career at a keyboard). I've often said that typing class in junior high was the single most useful course I ever took in school. I mean it.
Keyboard has a slight tilt, rubber feet, wrist rest, and is heavy enough not to go sliding around. Backlight goes from zero to quite bright and is evenly distributed across the keyboard.
It's on sale currently for around $23 about a $10 discount from whatever the usual price is at any given chaotic moment.
Eight colors, eight intensity values. No memory per se of backlight settings, but I've found for a standard Linux suspend the backlight goes off in suspend and comes back where you left it on resume, which is just fine. I was able to go back to full speed typing on this keyboard instantly, as opposed to the previous one that had some keys in odd places that were really pissing off my muscle memory.
