The Apple Pro mouse was beautiful, simple and only had one button. Its greatest asset was its greatest drawback, and although the design was superb, two buttons and a scrollwheel are too much functionality to give up.
Years of speculation have ended with Mighty Mouse, which preserves the simplicity of the design but exceeds the functionality of even a scroll wheel mouse.
Using technology patented by Apple a while back, not dissimilar to the scroll wheel technology for the iPod, this programmable rodent can do just about anything. Maybe it’s not quite as beautiful as the pro mouse, but this combination of ergonomics, aesthetics and functionality is huge step forward for perhaps the most important part of the human-computer interface.
The only thing holding me back from getting one is the thought there might be a bluetooth version around the corner.
