They've skirted the line many times while also frequently releasing great products that combine both. The apple III overheated because they didn't want to put a fan in it for aesthetic reasons. So did the original Macintosh, alright to a less problematic degree.

I honestly don't understand Apple's apparent disdain for more than one mouse button though. The OS and apps support extra buttons, everyone knows how to right click by this point, what's the benefit? At one company where I worked everyone had a MacBook, apple monitor, apple keyboard, and a white Microsoft mouse.
