The Logitech Cordless Presenter ($180 street) is the Vegematic of presentation remotes. Not only is it a remote presentation controller, but it also becomes a cordless optical desktop mouse when you flip a button and slide the device on any flat surface. Since this is a Logitech product, you know the design is gorgeous. The zippered neoprene carry sleeve, however, just barely holds the husky remote, the Bluetooth USB receiver, and USB extension cord. You wont find fabric stretched this taut until the next Sports Illustrated Swimsuit issue ships. For all its bulk, the Logitech pointer has the fewest features of the three remotes, with controls for only presentation forward and back and for a laser. There are ultra-sensitive up-down scroll buttons—theyre active in mouse mode only, but switching is quick. If you install Logitechs software, you can reprogram the buttons, but you cant activate the scroll buttons in presentation-remote mode. Only Logitechs device has a dedicated Off button, which keeps the battery from wearing down if the laser button is accidentally activated in a crowded laptop bag. Unless you want a cordless mouse at the same time, though, the Cordless Presenter is pricey for what you get. If youre interested, dont be scared off by the Bluetooth technology; setup here is truly foolproof.
