I have reviewed Microsoft's first rechargeable, wireless mouse. The new mouse uses Microsoft's second-generation laser optical technology, has a 2.4 GHz Bluetooth connection, a stylish brushed-aluminum finish and has updated IntelliPoint 6.0 software features. Here is an excerpt:

If you want to customize your mouse, you will have to install the new IntelliPoint 6.0 (about 45 MB), which does not require a restart. To customize your mouse keys, select either "Mouse" for the Control Panel or "Microsoft Mouse" from the program menu. On the buttons tab you can click on the different buttons and reassign the keys to a variety of functions. You must use this software to assign the performance slider and instant viewer. In this software you can also change your pointers, other pointer options, view which hardware is connected, change scrolling options, etc. The software is easy to use and is required for advanced functionality of the mouse. The instant viewer feature is pretty cool - you click the tilt wheel and all the windows you have home are brought into one easy view (see below). The magnify tool is the right button, and is the same as previous versions. Of course, you can reprogram these as necessary. Another feature is the performance slider, where you can choose between longer battery life and greater accuracy.
