This is not new technology, but as of a few minutes ago it is new to me. I finally swung by the Apple Store and picked up a Magic Mouse of my very own. It took all of 30 seconds to unpack it and get it paired up to my MacBook. I’ve been using it for all of five minutes but I’m already ready liking the way the multitouch gestures work. I had to enable right-clicking in the preferences (what’s up with that, Apple?), and so far I am just using the default gestures.
One of my concerns was how well the Magic Mouse would work with Firefox, but I needn’t have worried. Scrolling works fine with either one or two fingers, and even the swipe left and right works in Firefox. I’ll have to hold off final judgement as to whether it’s worth the $69 I paid for it, but so far it’s been pretty nice. Before anyone asks, yes, you have to remove it from the plastic case before using it. :)
