We could have guessed that it would have been Apple that would bring the world a better mouse. The sleek Magic Mouse, with its not unexpected modern design, has a laser-tracking engine, a seamless multi-touch surface and it’s wireless. The company says using it should feel ‘like magic in your hands’.
The laser tracking feature means that the mouse can be used without a mouse pad and still be very responsive. According to Apple, the multi-touch surface "brings a whole new feel to the way you get around on your Mac." As for its wireless capability, the Magic Mouse will be connected to your Mac up to 33 feet away, which is more than adequate for most offices or homes.
Users can also adjust the features of the mouse to their unique needs. For example, you can choose one button click instead of two. That's similar to changing how a touch pad works on a laptop/net book.
