It’s a reversal of almost a decade of trends in mobile computing, a decade that saw our phones get ever faster while our laptops and other PCs felt like they just wheezed along.

For everyday tasks both at home and at work, we have long had a choice: pull out a heavy brick with a noisy fan, a pixelated display, a few hours of battery life and a tenuous connection to the internet; or reach for that instant-on, always-connected, app-stuffed supercomputer in our pockets.

Laptops survived mostly because they’re better for heavier jobs: Their screens are bigger and physical keyboards are better for productive and creative tasks.
