This feels simple and powerful for a post about UI. The old Kindles had full keyboards! I really hate this trend to "Do everything with one button." So many devices have one button and different LED flashing patterns. LEDs are seriously cheap, cheap enough you can just add a few more to make the interface not-garbage; where I don't have to memorize a lot of rubbish. A great example: The Crafty Vaporizer. It has one button you push to turn on, hold to turn off, double tap to use the boost temperate (which can be changed from the mobile app you pair it with. WTF?) Compare that to the Boundless CF Vaporizer. It's an exact clone except it has multiple LEDs, all labeled, which can indicate temperate and battery life. One button is stupid. Touch screen instead of hardware buttons for the most common tasks is stupid (I'm looking you Telsa Model S) and removing hardware buttons for simplicity is sometimes a great idea, except when it's a horrible idea, which it more often is.
