Simply choose to setup a new Bluetooth device (via System Preferences or menu bar), turn on the mouse, and it pairs up. Once the mouse is working, I suggest installing a third party tool such as MagicPrefs to enable extra gesture abilities (and more).

As with any Apple product, the first thing you notice about the Magic Mouse is the design. It has a very low profile (shorter than a MacBook Pro), and the top is just a solid surface without any buttons. This design is undoubtedly cool, but also practical. It's fully ambidextrous (you setup which side of the mouse is the left click in the preferences). The ergonomics do suffer a bit from the low profile, as least for my big hands. I'm used to a mouse that is much taller, which makes me want to rest my hand above the top of this mouse.

Although there is a lack of visible buttons, clicking the Magic Mouse provides a physical clicking action (unlike some of the previous Apple mice that simply made a clicking sound via a speaker). The physical click not only gives you good feedback on your actions, but also allows for extra touch-only gestures. And gestures is what this mouse is really about. Actions that would be assigned to buttons on other mice are controlled by swiping one or more fingers across the mouse surface. Apple's preferences allows for left and right clicking, vertical and horizontal scrolling (with momentum similar to the iPhone), and navigating (e.g. Safari back and forward). But the mouse has so much more potential, which is where third party software comes in. I am using the free MagicPrefs to add dozens of possible gestures which can be assigned differently based on application (or sets of applications).

Another set of adjustments that MagicPrefs provides are for tracking speed and touch sensitivity. The first is a big deal for the Magic Mouse. While its laser tracking system is very precise, it's also very slow. With Apple's tracking speed preference turned to high, it still feels like this mouse is being pushed through mud. MagicPrefs fixes that by allowing you to track much faster than the built in settings. The default touch sensitivity doesn't seem to be an issue to me, but I have heard of some people who need to turn that down a notch.

A few final considerations for any Bluetooth mouse are battery life and speed of Bluetooth connectivity. Apple claims 4 months of battery life (via two AA batteries) with normal use. After 4 days of use, the battery indicator reads 97%. Extrapolating that information out, that does come out to approximately 4 months. Throw in some lithium batteries, and this time may be even longer. On the Bluetooth connectivity front, this mouse is very quick at coming to life after turning either the mouse on, or waking the computer for sleep. In the latter case, I can pretty much use the mouse immediately. The Bluetooth range is listed at the standard 33 feet. But in comparison to the mouse I have setup with my MacMini media center, the Magic Mouse works much better at the longer distances.

This mouse is wonderful (once the third party software is installed). I have been on the lookout for a good Bluetooth mouse that has more than three buttons for years. With the multi-touch gesture support, the Magic Mouse fills that void with the elegance of Apple's design.

Pros	Cons
Multiple clicks and actions via gestures Physical click instead of electronic Tracks well over various surfaces Very precise tracking Great battery life Fast connectivity and good wireless range Ambidextrous setup available	Slow tracking Limited gestures built in Not the most ergonomical for big hands
