My take is that tablets are underrated, however I'd like to see more 'higher end' applications aimed at at 'lower end' tablets.

For me the magic of tablets is that they are low cost, so I'm not afraid of losing or breaking them. They don't become a nexus of further expensive consumption: adding an expensive case, particularly one with a an expensive and special purpose keyboard, just takes something sleek and easy to handle and makes it klunky and awkward.

Go to a hackathon? Get any Bluetooth keyboard and mouse and a $5 plastic clip from Amazon Basics and you've got something sleeker and more stylish than any Macbook or gaming laptop with which you can connect to a powerful desktop computer or a cloud instance that is anywhere from 50 cents to $4 an hour depending on your thirst for power.

I started out with a B&N Nook, then Amazon Fire Tablets (amazing value for the money), then iPads, I had bad luck with my last iPad (either lost or stolen) and figured I'd use an old Samsung Galaxy tablet I had kicking around. Every time I got an iPad I looked at my options, hypothetically I thought I might like the Pro but a new Pro is crazy expensive (I couldn't afford to break or lose it) and an old Pro in my price range is old technology.

(Note I'm a little weird because I've never owned a smartphone with a plan. Carriers choose not to serve my valley, why should I get an expensive plan? My data plan is WiFi, and my phone plan is Skype)

The Pro, like the AVP, also seems hobbled by Apple's short-sightedness. A device that expensive, with hardware as capable, should be able to do 100% of what a MacBook can do. It should be able to completely outdo the Microsoft Surface, but it doesn't.

I mostly agree with everything you said. However at this time I wouldn't risk my business by releasing software primarily targeting tablets. The rate that people pay for iPad specific software is too low.

95% of the development work I've done in the past 25 years has been for the web platform. I don't see that changing. If you make desktop web site that are WCAG AAA compliant they also are great on tablets for XR. (In the limited sense of "windows hang in space that you can use like an app)

I haven't wasted a minute arguing with the app store if I'm allowed to do this or that. For what? So I can add an icon to an over-crowded home screen that is already crowded with twisty little icons that all look alike? So I can spam people with unwanted notifications?

I can even use the web platform to make real immersive applications for XR, though I'm currently trying to figure out the exact memory limits to make things work on the MQ3. I've got a vision in my mind of an app that provides a visually intense and expressive experience on phones but also puts you in a world if you've got the hardware for it. The web platform is totally up to it, I just have to figure out to do it.
