Value and Verdict
There is very little that the Logitech Illuminated Keyboard does wrong. It looks excellent, can be used at any time in any lighting condition, and provides an excellent typing experience. That said, the Logitech Illuminated Keyboard doesn't have perfect build quality, and its features beyond illumination are lacking.
And that's what makes the Logitech Illuminated Keyboard's biggest flaw become apparent - it's price. The MSRP is $79.99, and most retailers seem to keep within $10 or $15 dollars of that price. There are plenty of decent keyboards available for $20 or $30 dollars, and many of them offer more features (besides the illumination). The price of this keyboard also puts it up against gaming keyboards. The G15, which provides good typing feel, tons of macro keys, illuminated keys and a LCD screen, can often be found for only $10 dollars more, and at some retailers is actually cheaper.
This makes the Logitech Illuminated Keyboard something of a niche product. Specifically, those who own Thinkpads and want a similar typing experience for their desktop will quickly fall in love with this keyboard. It replicated the quiet, highly tactile feel of those keyboards almost perfectly. Those who want a great typist keyboard and are willing to spend a premium for it will also find this keyboard a good buy. The average user, however, would be better off with a cheaper media keyboard such as the Logitech Access or one of Microsoft's wireless multimedia keyboards.
