The value of a product is the number of problems it can solve divided by the amount of complexity the user needs to keep in their head to use it. Consider an iPhone vs a standard TV remove: an iPhone touchscreen can be used for countless different functions, but there’s very little to remember about how it works (tap, drag, swipe, pinch). With a TV remote you have to remember what every button does; the more things you can use the remote for, the more buttons it has. We want to create iPhones, not TV remotes.
I kinda disagree with this? Like: the iPhone screen is good for dsiplaying and interacting arbitrarily, but bad for efficient/dedicated use. The buttons on a TV remote are unambiguous: they have labels, it’s clear when they are pressed or not, there is no lag on input/output/state.
I think dedicated functionality should be extracted from iPhones into TV remotes. Dedicated hardware greatly reduces the complexity (thus increasing the value).
