I am so getting that... one of these days.
I have an illuminated keyboard that I bought several years ago (for the same price), and that Logitech one seems to address all the complaints I have about mine:
1) Mine is a bit compact like a laptop keyboard, but with a numpad, resulting in some odd placements for some keys (e.g. for some reason the key that makes these symbols "|" and "\" is by the LEFT alt button as well as in its usual place above the enter/return key. There is also no gaps between the number keys and the F# keys, making it hard to press the correct function keys by touch, which results in a lot of "fat fingering" the function keys when trying to press a number, bringing up help menus and other unwanted side effects). The Logitech is a full size keyboard, so everything is where it belongs.
2) The letters are starting to wear off some of the keys. The Logitech letters are laser etched, which I believe means they won't be rubbing off or wearing out.
3) I find I still don't like typing in the dark with mine because the light from my monitor is so bright in my eyes that I still can't see very well the keys on the keyboard, so I usually have a light on in the room. The Logitech lights up only the letters' silhouette and appears brighter, making it easier to identify letters in the dark.
There's a video in the image gallery where he presses the buttons. It seems to be fairly standard keyboard, but I'm not sure what you mean by "clicky." I think it might be quiet, but it seems like you would definitely be able to feel the button depress. But that's also how laptop keyboards are (you can feel them press down and come back up, but they're kind of quiet), so I'm not sure if it meets your "clicky" requirement.
What would be cool is if I got that and the mouse, both coming with a unifying USB receiver, then I could put the USB receivers into two computers and control both of them with the same keyboard and mouse without having to disconnect anything. I might have to get creative and use Skrommel's Toddler Trap on the PC I don't want to be controlling at the moment, but I still think that would be cool.
