[edit] Features
The MX Revolution and VX revolution are wireless, USB 2.0 mouses which operate on the 2.4 GHz band with an operating range of 20 - 30 ft. The mouse is powered from a non-removable, rechargeable Lithium battery. The optical sensor employs a small infrared laser with an advertised sensitivity of 800 dpi.
Other new features include single-button web search, a document quick-flip side wheel, and ergonomic enhancements. The mouse has a total of seven buttons, all of them programmable except for the right and left click.
[edit] Scroll Wheel
The most significant new feature of the MX Revolution is the "hyper-scrolling" scroll-wheel, which enables the scroll wheel to spin freely for several seconds, enabling rapid scrolling through long documents or spreadsheets. The design of the scroll wheel a radical departure from existing scroll wheel designs. In order to maximize free-spin time, the MX Revolution employs a rubber-coated alloy wheel which weighs 14 grams, nearly seven times as much as conventional all-polymer scroll wheels.[1] In order to maintain the feel of a lighter, conventional scroll wheel, the wheel is counterbalanced by a spring-based suspension system, which also allows the travel required for push-to-click operation and horizontal scrolling.
There are three ways to toggle between normal operation and "hyperscrolling": (1) clicking the scroll wheel, (2) using included software to tie scroll wheel operation to specific applications, (3) auto-detection of rapid scrolling. The transition between the two modes of operation is controlled by an internal switch which delivers current to a small DC motor. In the conventional mode of operation, the wheel's motion is governed by the action of a small spring-mounted ratchet mechanism. When the switch is activated, the ratchet mechanism retracts, allowing a free spin for up to seven seconds. [2]
[edit] Marketing
The MX Revolution is marketed as a general purpose mouse, a product refresh for the Logitech MX1000. The MX revolution is not marketed as a replacement for the Logitech G7, Logitech's gaming mouse. The first suggested retail price ($99) suggests that the MX Revolution is targeted towards enthusiasts and early adopters. Logitech's marketing campaign touts the Revolution as the "World's Most Advanced Mouse." In marketing materials, the scroll wheel technology is trademarked as the MicroGear(TM) Precision Scroll Wheel. The software-hardware mechanism for switching between the two is trademarked as SmartShift(TM), using Logitech's SetPoint software. The VX revolution, unlike the MX revolution, features no Smart shift technology.
