Fremont (CA) - Computer mice are fairly boring devices and companies have tried adding lasers, vibration sensors and scrolling wheels to spice them up. Now Logitech has announced its new MX and VX Revolution mouse line that has not one, but two metal scrolling wheels that can scroll through thousands of pages in a single flick. The wheel can also select words inside of documents or search the Internet.

The new "MicroGear" scroll wheel can spin freely for up to seven seconds and Logitech claims that a single flick can go through "10,000 lines of Microsoft Excel". In addition to the free-spinning mode, the wheel has the traditional click-click mode when spun slowly. The modes are automatically selected by the mouse depending on how fast the wheel is spun - fast spinning makes the wheel go into free-spin mode, while slow spinning puts it into click mode. Users can manually select the mode by clicking the wheel once.

Logitech has also added a "One-Touch" search button just below the scroll wheel. Users can set this button to bring up their favorite search engine such as Google or Yahoo. A side wheel on the left side of the mouse can be used to zoom into photos or switch between applications.

Logitech also announced a smaller notebook-sized VX Revolution mouse which includes a micro-receiver for wireless operation. The mouse has the same MicroGear wheel as the larger VX mouse, but does not include the side wheel.

The Logitech MX Revolution mouse is available now for $100 while the VX Revolution has an MSRP of $80.
