The concept of this keyboard positioned between a real keyboard and a fake Pc laptop keyboard is quite misleading. Indeed the interface is surprising and sacrifice the numeric keypad for use via a pc fixed very disabling for me. A large area "touchpad" why not but why a keyboard so narrow and "small" ..? The backlight is nice but still insufficient because the red markings are completely invisible in dark surroundings .. His "touched" is nice and it has good reactivity.
