Wireless Mighty Mouse full review
We won’t delve into the Mighty Mouse’s strengths and weaknesses as Apple’s been shipping the wired version with Macs for a while now, so many are used to its idiosyncrasies (by that we mean it’s damn difficult to use at first).
A bonus with the wireless version is that a laser replaces the regular optical tracking. This provides 20 times the surface sensitivity, eliminating the problem with the pointer skipping around the screen on some surfaces. It also uses Bluetooth to conserve battery life and a battery meter is included in System Preferences.
