The Apple "Magic Mouse" arrived today. Two words: A Mazing. Scrolling is like a whole 'nother world and the ability to zoom the screen by holding down the "option" key is just silly. This thing rocks. Hard. Like Metallica trying to prove they're a better band than Anthrax.
UPDATE: There is something of a learning curve in using a new mouse, tweaking the tracking settings for example, but even after this short time of using the new mouse, I have to say - this is brilliant. Guinness scientists must have invented this. Scrolling across the smooth top is going to become the new, albeit pricey, paradigm for mousing.
