There is a problem with the uni-button trackpad trend on PC laptops. Thats the what happens when you don’t have a strongly developed point of view. Blindly emulating Apple’s trackpad for a system with two buttons is a problem because you can’t distinguish between two buttons with tactile feedback. With a Mac, you can get away with a uni-button trackpad because there is only one click action, with the modifiers being how many fingers are on the pad, not where on the trackpad you click. This is why building systems without a point of view is dangerous – you’ve now caused a regression in UX, because you did not fully grok the why, instead you just went ahead and did the what. This can be applied to many engineering systems.
