Logitech unveils its highest-end mouse yet?the MX Revolution Cordless Laser Mouse. The bells and whistles packed into this mouse sound like the Fourth of July. No hot dogs, though. At the top of the list of innovations is the huge upgrade to the scroll wheel, which has two modes of operation?line-by-line scrolling and free-spin scrolling. Free-spin scrolling allows the scroll wheel to become a flywheel capable of traversing thousands of spreadsheet rows or hundreds of word-processing pages with a single flick. Other advanced new features are the document quick flip wheel (or button), one-button search, and a zoom slider. All of these buttons could add up to an overload of options, yet with Logitech's software, SetPoint, customizing them to fit your needs is a snap.
