As rumored, Apple has just introduced a new mouse called the Magic Mouse. This mouse will bring Multi-Touch capabilities to desktop Macs for the first time, something that the iPhone has had since its release in June 2007 and the MacBook Air since it was released in February 2008.
It loses the scroll ball found on the Mighty Mouse, but adds support for scrolling gestures. This mouse is also wireless, using Bluetooth, and has a four month battery life. This mouse is available for $69 in late October, and requires Mac OS X Leopard 10.5.8 or later.
