as a software developer for more year then I care to remember I purchase this illuminated keyboard because I sometimes have to provide software support during the night and I hate to turn on a lot of light . this keyboard seem to be of excellent quality , I like the position of the multi-media key on the left and right side of the keyboard . the back lighting be very easy on my eye and make use this keyboard in low light condition very pleasant . I be use this keyboard on a desktop computer with Windows Vista and there have be no issue with the operating system and this keyboard . I would strongly recommend this keyboard to anyone with a interest in a illuminate keyboard .
