I helped a friend set up her new 27″ iMac last weekend, and it came with the coolest new mouse… The Apple Magic Mouse.
The mouse is the button, plus it has no scroll wheel, but you can use it to scroll up, down, diagonally and sideways. Comes in one color, wireless Bluetooth, but right now is only supported for use on a Mac (Windows support is coming!) The way it works is similar to the MacBook trackpads with multiple-finger functions, but that is a couple of steps above the trackpad on my getting-older-by-the-day PowerBook G4! I want one!
Actually, these would be great for use at work; seems like I’m replacing a mouse somewhere in the building at least once a week. The failures are usually with the scroll wheels, and the Apple Mighty Mouse with its tiny little scroll ball is the worst offender. The Magic Mouse with no external moving parts should be nothing but great! And as great as this mouse is, the tablet computer that Apple is expected to announce should be nothing less than amazing.
