I'm writing this from a pc. Because I'm a pc. But Apple takes the cake for the best mouse to ever be designed. The Magic Mouse (MM) is Apple's newest mouse, totally eliminating all mouse buttons. [Price - $70]

The Magic Mouse has a four-month battery life, communicates via bluetooth, and a laser tracking pad on the bottom. Instead of pretending the buttons are there, like on a normal, two-button, scroll-wheel mouse, they're everywhere. Using a multi-touch system (see pic below for what that actually is), the user interface is literally anywhere on the mouse. It reacts to your actions in the most user-friendly (and adaptable) way I've ever seen. [See demonstration vid at bottom of this post.] If you're wondering how multi-touch (the same touch interface that apple portable media devices use) actually works, checks this out.

( This has everything one would expect when logically analyzing how a touch sensitive object works. But who does that? :0 )
But wait! What if us jealous pc's want in on this? Well, never to be left out, all too helpful pc owners have obtained the .exe's for the drivers on the mouse and made them available on the internet.

Step 1. Purchase the actual mouse at your local apple store.
Step 2. Go
here.
- And that's about all I can say on this site, unless I want to get cited for telling people how to hack apple stuff's. lol.
Once again, to give credit where credit is definitely due, Apple has made a sleek, affordable, innovative product that many people should pick up. Now, as long as they don't start charging for anything (i.e. updates) afterwards...
