Anything that makes Dorico adopted more widely is good so the tablet support for the iPad is good. But remember also that there are many tablets running the Windows OS. And the main operating system on the planet by a huge, wide margin is not the Apple OS or Apple iOS, it is also the Windows OS.

Personally, I will NEVER EVER use an iPad or even a Google Android tablet or even think of buying an Apple computer running the Apple OS simply because, when you use Windows, most of the software is first available on the Windows OS and there are so many more applications on Windows than on any other OS by a huge margin.
