For your consideration: another Logitech keyboard. It’s the Wireless Illuminated Keyboard K800, and as the name implies A) it’s wireless and B) it’s illuminated. Aside from the wireless-ness and illumination, it seems to be a pretty standard-issue keyboard. Nothing wrong with that.
The illumination is a little bit different this time around in that it’s not a binary situation. The keyboard has built-in sensors that detect the amount of light in the vicinity. Lots of ambient light = very little to no keyboard illumination. Typing in darkness (good think for PerfectStroke, which makes your typing quiet)? On turns the illumination.
You know what I mean. Further words will only muddy the issue.
And… that’s it.
