I like the Mighty Mouse, my grip is pleasant with good roundness and easy access to all functions (by cons must set the right click on the computer, it is strangely off base). Too bad the famous scroll ball, usable on both axes and very practical Indesign, clogs quickly. His life was then try somehow lengthen with grandmother tricks that circulate on the net, until she finally makes the soul (between 1 and 2 years, depending). Personally I am in my fourth model. Shameful.
