Interesting retrospective presentation. But I have two quibbles with the stated facts. First, some pre-iPhone smartphones had touchscreens, but required a stylus to be effective. Secondly, tablets weren't being ignored pre-iPad. They just weren't being done particularly well, outside of a few industry-specific verticals. BTW, these aren't the first instances Apple changed the design norms for the mobile industry. Anyone remember what laptops looked like before the PowerBook 100? Moving the keyboard forward towards the screen to make room for the trackball provided the rest of the laptop manufacturers the template for laptops that continues to be used to this day. We benefit because we have room to rest our wrists between typing spells.
