Ripped off Slashdot: "Hot on the heels of the announcement of x86 Macs, Apple announced a multi-button mouse, known as the Mighty Mouse. It appears that the entire surface is touch-sensitive, allowing the mouse to be programmed as a single-button, multi-button or scrolling device."
Here's a review. If Apple comes up with a Bluetooth version and proper Windows drivers, I might even consider buying it.
