The thing is iPads offer good experience as a tablet but when you want from it a bit more Apple doesn’t allow it because of their Apps Store policies.
Personally I think iPad could be a great device for coding on the go. But the fact that we can’t install anything outside of apple’s control blocks this option.
RDP or SSH is nice but it relies on internet connection. I’d like to use the native power of the device. With M1 there’s no reason it wouldn’t be able to do so.
Their arguments about security to sounds more like bunch of excuses.
