Many experts say mobile devices such as smartphones and tablets will replace the PC. Some think this will take a matter of months; others would say a few years. I would argue that both camps are wrong: I believe it has already happened.
The smartphone actually replaced many of my other products, not just the PC. It became my camera, MP3 player, portable video game console, newspaper — and for some, it even replaced the TV. This is why the idea of mobile first was so easily accepted in the industry and why everyone invests in building mobile apps for their business.
