Features & Specifications
The Logitech Illuminated Keyboard is very thin with a profile of only 9.3mm. A transparent border around the keyboard adds looks, but does make the keyboard about 1/4 of an inch larger than it needs to be on the top and sides. The keys are all backlit and the backlighting is adjustable. A button on the keyboard allows the backlighting to be adjusted through three different brightness levels or turned off completely.

Logitech uses its PerfectStroke key system with micro-scissors for increased key travel and improved typing feel. Logitech says the keys are good for up to 10 million keystrokes. Other features include integrated media controls and more.

In Use
The first thing you notice about the keyboard is how thin it is. The 9.3 mm profile makes for a very flat and comfortable typing position. The PerfectStroke key system provides one of the best keyboards for typing I have ever used. The keys are very responsive, have great travel, and offer a slight click when pressed. Overall tactile feel is excellent. The typing feel is so good that the Logitech Illuminated Keyboard is now the only keyboard I type on.

The backlighting is done in white, which is a welcome change to the mostly blue backlighting we get on gaming keyboards. The backlighting is bright and evenly lights the keys of the keyboard. Fans of wireless keyboards may be disappointed that the keyboard does connect to the PC via USB, which is the sacrifice you make for backlighting.

The one-touch media access keys require the use of a FN key like you find on many laptop keyboards. A full array of media control keys are offered and keys for one touch access to favorite applications and web sites plus shortcuts to Windows Vista features like Gadgets and Flip 3D.

I did find a few quirks with the keyboard mostly centered on Logitech's odd key arrangement for a few of the ancillary keys. The delete key is twice as tall as the typical delete key thanks to the moving of the insert key from the left of the Home key up above its typical position and in line with the function keys. The keyboard sheds a dedicated scroll lock key -- certainly not a big loss. Scroll lock can be activated via the FN keys though.

The biggest key issue I found is that the backspace keys is about half the width of the typical key. Due to this I ended up hitting the "+" key on occasion when reaching for the backspace key. After using the Logitech Illuminated Keyboard for a few days I grew accustomed to the smaller backspace key.
