It is a great tablet experience! They could have a dual boot option where you get a MacOS for real work. Otherwise you are right, don't try to make real work happen in the current form. SO MUCH FRICTION to copy and move a file around for example.

The bulk of my use is strictly tablet stuff and I think it is really great at that.

Exactly. The OP complaining that it’s cumbersome to use Excel, well yeah, but the things tablets are designed for; dragging, drawing, tapping etc. It excels at (pun intended)

Sure, but I think the overall sentiment is that Apple hasn't really pushed the iPad any further as an input device. It still does those drawing, dragging and tapping things well, but why haven't they pushed those gestures to work with context menus or have some unified purpose? In some ways, the iPad is still the bare minimum of being a tablet, but it's mastered that concept. As Apple continues to market it as a "computer" though, they have a responsibility to improve the computer aspects of it: file management, improved user control, and developer solutions are all weak or missing links in the chain here. Sure it does tablet well, but it sucks at computer.
