Apple Wireless Mouse

The Apple Wireless Mouse is a one-button mouse built for Macintosh computers. It was released in September 2003, although it is not widely recognized that it was Apple's primary wireless mouse until 2005. It interacts over Bluetooth 1.1 wireless technology. It included two non-rechargeable AA lithium batteries, and had a power switch on the bottom that also protected the optical sensor while the mouse was not in use. While the industrial design of the Apple Wireless Mouse was handled entirely by Apple's in-house designers, some of the hardware was engineered by Sparkfactor Design. Apple model numbers include A1015. 
The Apple Mighty Mouse, a multi-button mouse with a scroll ball, was eventually released in a wireless version.
Apple eventually discontinued the Wireless Apple Mouse, replacing it with the Wireless Mighty Mouse.
Criticism.
Like its wired counterpart and many of its predecessors, the Apple Wireless Mouse was heavily criticized for its single-button layout. Apple remedied this with the four-button Mighty Mouse.
