I have the Logitech S 530 setup running on my Mac-mini, and I really like it. The receiver sits about six feet away from the keyboard and mouse, and it on the extender supplied with the kit. It works initially, but the software that comes on the CD (in my case, anyway) was not compat w/10.4.8. But I meandered out to the Logitech site and found an upgraded one, installed it, and now it shows up in the very bottom on the System Preferences. It takes advantage of some extra keys and buttons on the keyboard/mouse. The mouse is a laser mouse, btw, and works extremely well. The keyboard is a slim design and I haven't had any issues with it, but these are usually personal preferences. One other item, the kybd uses AAA batteries, the mouse AA's. The setup I bought came standard with Duracell's, and not some el-cheapo's. Been running this for a month now, and still on the same batteries, although I did pick up some replacements ready for use.
