To me, it doesn't matter how powerful the iPad is if the software experience is subpar. Multitasking is cumbrous enough that it might as well not exist, multi-display setups can only mirror at a fixed aspect ratio, it lacks multiple user profiles requiring a family to be under a single user, and the few apps that take advantage of the keyboard/trackpad are nowhere similar to their desktop counterparts. Take Excel for…
I can think of one use case where it could be nice - content creators. For example I like to noodle on guitar and frankly guitar interface + iPad > laptop. Likewise for video editing, photo touchups, etc. I can see iPad for creatives using more processing power
- you need a dongle to plug the interface and the charger together (maybe other interfaces can supply power but mine cannot)
- my interface also behaves as an usb audio device (I suspect all of them do) but iOS does not let you choose audio out through internal speakers or airplay if the usb audio device is present
- some apps don’t support multiple inputs and default to the first input (which on my interface is mic in), GarageBand does not have this problem
Of course this is not a problem for things like digital pianos that just explore midi over Bluetooth.
