The promise has been there since stuff like 8tracks on the iPhone 3G, and various Audio Units already on iOS. But I’ve always found the workflow very limiting or clunky. (Edit: I’m a Logic Pro user on macOS so my comments reflect getting things into that specifically)
The divide from putting down an idea when it hits, to working it into something, has always been really high.
Having something where I can potentially work out an idea with just my iPad , and then take it to my desktop is really exciting to me.
FCPX seems neat as well. I doubt it’ll be something people use in touch mode, but I can see some folks using it for quick on the go edits for things like social media stings. Go to an event, shoot, edit and upload. I don’t see it being used for more than that level of work.
But also, as much as both the things I mentioned are very spur of the moment things, I think the real value here is having a step ladder through the ecosystem.
A lot of people, especially youths, only need an iPad for more of their computing use. Having more pro apps on the iPad signals to them that they can shift more of their computer life to it. A lot may just even need to add a Bluetooth keyboard and mouse.
Conversely, the people who do want to use it more seriously after whetting their teeth on the mobile platform, will then see the Mac as the next logical stepping point.
It’s a smart way imho to get people on either side of the fence to consider the other side.
