A few years ago people were talking about convergence of phone/desktop, i.e. you plug your phone into a big screen and keyboard and it’s now your desktop computer.
Mobile apps are shit for that. Sure, my phone is powerful enough to browse internet, play video and music but on desktop with mouse/kb it’s just weird and funky. And I’m not even talking about any productivity software which is straight impossible.
Excel enabled non-programmers to create basically any app as long as they are fine with a cell-based UI. Same with Access and CRUD apps. I know people love to dunk on M$ here, and for good reasons too, but these two programs are probably responsible for a decent chunk or PoC/v1 projects worldwide.
