Foldable phones have a chance if their prices can drop fast enough – but will business users be convinced?


Microsoft’s ill-fated Surface Duo couldn’t convince many folks that it was superior to foldables, but it started out with a few advantages over them. The hinges could rotate 360 degrees.

Managing multiple apps was easier, its screens had a 4:3 aspect ratio (arguably better for productivity if harder to grasp), and it was a few hundred dollars cheaper, in part because it lacked an external display. That omission also helped to make it significantly thinner than Samsung’s contemporaries: the Galaxy Z Fold 2 and 3.
