Review on Logitech Advanced Illuminated Wireless Keyboard Computer Accessories & Peripherals for Keyboards, Mice & Accessories by Stanislaw Puzyna ᠌

You may first be put off by the unfamiliar layout of the controls and the close proximity of the function keys to the main unit, but after about a week, you won't even give them a second thought. Even without illumination, the key labels should be legible in a well-lit room. If you care deeply about using a keyboard that solely has English letters, you should know that this is not always the case. All buttons are functional after booting up on Linux; certain function keys required tweaking, but hey, Linux.
