We live in an app-centric world. Even those products and experiences that advertise focusing on your documents first mostly stop at the boundaries of the app. Crafting such apps isn't easy, especially when you want to support all the incompatible platforms in use today. There have been and continues to be numerous attempts at crossing those platforms but one solution seems to reappear time and again, a solution harnesses the power of the web, the one platform available on all platforms. Progressive Web Apps, as the current incarnation is called, has definitely gone a long way from the earliest Java applets but is still far from becoming the all-in-one solution its proponents try to advertise.
