The Lenovo Multimedia Remote has 2.4GHz Wireless Keyboard with a trackball combo. It’s designed to be used with your palm, and as a result of design engineering, it’s sculpted with a compact style. This wireless remote has a range of 10 meters, and is nice for living room multimedia.
You can connect this to a Window XP, Vista or 7 load PC with a USB dongle, but I’m assuming that means you can plug it into a Mac. You just won’t get any back-end software to tweak its settings. Once connected, this multimedia remote can also be used for using multimedia controls on the PC like with Windows Media Center. The Lenovo Multimedia Remote with keyboard is already available for purchase for $60. www.lenovo.com
