And right click works. WORKS.
Sure, it WORKS, but it's ergonomically broken, especially for those who have switched from PC platforms to the Mac. Most traditional 2-button mouse users permanently rest their index finger on the left-click button, even while right-clicking. You can't do that on the Mighty Mouse, because the sensor will interpret every click as a left-click in that scenario. It forces you to lift your index finger away to perform a right-click action. I don't know about anyone else, but if you have grown accustomed to traditional 2-button mice over the past 15 or so years like I have, it's a very hard habit to break.
In fact, with the MM, I found myself turning off the "click zones" and just performing Cmd+Click actions instead (like I'm used to on the laptops) because it feels more intuitive for some bizarre reason.
Let's see....what else? The squeeze buttons are awkward and it feels as though I'm going to break the mouse every time I use it. The glossy, candy white casing makes the mouse slip out of my hands frequently (rubberized grips, Apple!). The scroll ball is a good idea, but poorly executed. It needs to glide more smoothly and feel more robust. And while I'm on that subject, the mouse simply feels cheap. That's unacceptable for a mouse that costs $50.
My $40 Logitech laser mouse is much better. It has a nice, balanced weight to it and I never have to second-guess what it's doing. I've come to the conclusion that Apple's input devices are designed solely to make a fashion statement. I can't imagine how anybody who does professional media work like I do can live with the Mighty Mouse.
