I'll share the good part first: I read the funniest thing in a review of the Mighty Mouse today that had me laughing in spasms like an idiot for an hour. People at work had to come over and tell me I was having too much fun and would I please shut up so that they could get back to work. The review was in engadget. It's no. 6, Dave. I'll let you read it for yourself: http://www.engadget.com/entry/1234000450052910/ Two days now of using the MM and reprogramming my neural pathways. I now "get" that you use it as a single button mouse like you would the Apple Pro mouse most of the time and just move your hand slightly differently when you want the right click. The side squeeze button requires way too much pressure to be ergonomically right for me save for occasional use. It keeps you from accidentally doing the squeeze, but for someone like me who's on the computer seven days a week most of my waking hours my hands hurt at seemingly insignificant force levels, so I won't be using the squeeze buttons much. You have to actually move your hand and hold the mouse in a totally different way to use the squeeze buttons and the scroll bead. If the squeeze buttons were just a little bit farther forward it would be an awesome feature instead of a "Stop: I will now use the squeeze buttons" feature. But it's the scroll bead that I find most annoying. With a real scroll wheel I don't have to move my hand. With this I have to use the tip of my index finger. I have a conspiracy theory that the MM was designed by a woman.
