| Bottom line | Info unavailable | Kensington resurrects a dying breed with the SlimBlade Trackball, but the potential of its unique shortcut buttons devolves into a mess of clumsy extra functions and awkward movements that restrict productivity. | Info unavailable | Logitech's MX 1100 wireless laser mouse is the best in its class thanks to a wide array of features that make navigation easier. You have to pay for all of that capability, but anyone who puts serious time in front of a PC will appreciate what this mouse can do. | Info unavailable |
