The first quality is Illuminated Keyboard typing comfort which is by far the best I know. It has the qualities of a good laptop keyboard without the drawbacks. The run button is set properly, neither too much nor too little. Despite a relatively short stroke, we feel when a key has been hit with a slight depreciation difference at the level of comfort at the end of strike. It is difficult to convey in words the feeling, gently mixing and precision. I learned typing and I type quickly without looking at a keyboard, which always amazes my colleagues. I am particularly sensitive, even the manic typing comfort. This gives you an idea of my requirement in this area. However, I find the perfect Logitech except a button. The space bar is indeed "cheap", with a touch and indicating to the level of any brand of keyboard. It's not the cat, but it is a shame for a default button so used and on which we tend to hit harder than others. Still, the Illuminated Keyboard remains my reference, exceeding even the excellent keyboards of IBM Thinkpad laptops just before the sale to Lenovo. To compare against a keyboard that many people affected at least once in their life because he draws in a store and it is often exposed - you guessed it, the iMac keyboard, I will say that the Logitech plane far above, thanks to a race longer keys and better damping. The Apple keyboard has a "dry" side, frustrating as typing stopped very quickly. But I confess that the Logitech takes especially when using wide ten fingers.
The keyboard is particularly quiet, a factor which is my second selection criterion. When typing quickly, silence is all the more necessary to not have the feeling of using an old sewing machine. A loud keyboard with a modern PC, it is like driving a Porsche being dressed in rags. Certainly, one does not run slower, but still ... The Logitech is very quiet, except again the spacebar.
I find the design of the Illuminated Keyboard is stylish, with a good balance found in the search of a discreet beauty and find its place in contemporary interiors. The outline of the keyboard is made of a transparent plastic rim that provides a modern twist and is reminiscent of the recent LCD TVs. The materials used are of quality. Part wrist rest is made of a soft, non-slip surface for comfort. In short, it is the Logitech quality.
The backlight is adjustable to three levels and can be turned off. Personally, I pay on the average level. The highest level enhances the keyboard, but at the same time, he reveals light leakage between the keys. A backlit keyboard allows use in an unlit room. Thank you for sustainable development and at the same time, it's so aesthetic to see his keyboard "float" in the middle of the dark. I can not imagine me without returning to a keyboard backlight.
In conclusion, the Illuminated Keyboard worth the price even if at first glance, many will wonder if there is a reasonable purchase. A keyboard lasts for years and an investment in such a device is perfectly reasonable. I'd even have a better keyboard, but poorer mouse. The keyboard is an essential human-machine interface and increases the pleasure of using their PC, whether for leisure or work. It would be a shame not to find this keyboard a rare quality.
