Earlier quoted context omitted.
Actually, Microsoft came with "modern" smart phone much sooner. Actually too soon, technology wasn't there (price, computing power, size, weight, battery life). Apple never came first ... but often just at the right moment and had marketing skills to make it a new trend.
> technology wasn’t there Until Apple developed it. Those early iPhones employed a lot of tricks to squeeze usability, battery life, and performance out of underpowered devices. Prior smartphone attempts mostly applied PC-centric concepts to the device, it’s no surprise they ended up failing.
It was again the right time, when technology was there and Apple's skill was the ability to spot the moment when otherwise overly expensive touch screens can be cheapened by scale of production to acceptable level, had the marketing machine to sell an expensive device in millions at times, when most people were used to cheap cell phones for calls & sms.
