Walk into Best Buy or visit Amazon.com, and you'll find an endless selection of notebooks and desktops. But what about all the add-ons that can both help you in your business and add a little personal flair? Though the variety of peripherals is equally extensive, these are some of our favorites.

The three-piece SlimBlade Media Notebook Set ($129.99) from Kensington is the ultimate in wireless innovation. The keyboard pieces, including the optional media remote (sold separately, $19.99), are detachable and can be used individually or snapped together in your preferred order.

ATEN Technology's CS661 Laptop USB KVM switch ($99.95) connects two computers (any combo of laptops and desktops), allowing for simultaneously control of both computers, easy file transfer and sharing peripherals. Set one computer as the primary console, and the switch adjusts the resolution of the remote computer screen to that of the primary; then toggle between the two.

The Microsoft Arc Mouse ($59.95), with smooth and responsive tracking on nearly any surface, has a 30-foot wireless reach via micro USB transceiver. The transceiver can be left in the computer when storing or transporting (it sticks out less than a centimeter) or it can be stored in the underside of the mouse.

Rounding out the bunch is a unique device from CoolIT Systems, a company known for its computer cooling technology. Its USB Beverage Chiller ($24.99) makes a nice desktop addition for the hard-at-work entrepreneur. It keeps cold beverages cold and will also chill room-temperature beverages with a bit more time.
