I own an M4 iPad Pro and can't figure out what to do with even a fraction of the horsepower, given iPadOS's limitations. The rumors about an upcoming touchscreen Mac are interesting, perhaps Apple will deign to make their ridiculously overpowered SOCs usable for general purpose computing. A man can dream..
Questions for you: 1. If you don't know what to do with it, why did you buy it? 2. If you wanted a general purpose computer, why did you buy an iPad? 3. Which iPadOS limitations are particularly painful for you?
Browser engine lock-in - no Firefox+uBlock Origin = me no buy. And yes, there is Orion, which can run uBlock, but it and Safari have horrible UI/UX.
