Apple mice suck. Period. They're practically unusable, poorly tested, unreliable, overly expensive garbage. Problems with their pointer devices are noticeable to anybody withing the first 5 minutes of using the device. To make matters worse, the way mouse inputs are handled is similarly bad. Unusable and unpredictable acceleration curve with no exposed configuration to tune it, and decades of trying everything possible to avoid having a second button has created all kinds of nonstandard ways of handling right mouse clicks and all kinds of legacy keyboard gyrations for simple actions that could just be handled through a right-click context menu. Option-Shift-Command-Delete really, so I'm modifying a modification or a modifier key? Wow, that's totally discoverable. The semantics of such a command astound. (it's slowly improving, but right-click context menus are not really in the Apple culture).
It's bizarre because Apple is really the first company to design their devices around non-keyboard input, even going to far as to remove arrow keys off of the keyboard in early devices to force people to use the mouse, their touch devices have reinvented mobile computing, and their interface standards are extremely high, why is it then that the mouse I had with my original single body black and white Macintosh is more usable than anything the company has produced since the ridiculous hockey puck mouse in the 90s? Does nobody in the company actually use their products? Is everybody just walking around with MBPs using the trackpads?
One lesson to be learned though is that there simply is a certain amount of complexity you have to deal with in modern computing. You can shift that complexity around (eliminate the right mouse button, but then you have to have awkward and non-discoverable four key combinations), but it's very hard to eliminate it. Trying to find the optimal balance point that allows the best possible management of this complexity is hard.
