Already said being ironic, though I suspect there used to be some amount of users of Wacom but now switched to iPad. Personally I’m very muscle memory towards mouse, work in AEC industry, and drafting is my main concern. I think a iPad with pencil and a kind of trackpad functionality as input interface for Mac would be interesting for me: being able to precise draft and pinpoint select without the need to drag mouse would speed things up.
What exactly needs to be changed? The case volume is barely ok at the moment, meaning you can fit in a battery that is adequate to at least some but not all. I do want enough area to rest my hands on, I want a decent keyboard, I want a big enough screen and I want ports on both sides of the machine.
Maybe for you. 15" is the minimum screen size for me. The current 16" one would be good enough if it'd have a decent battery life. The new keyboard is so much better than the butterfly that it's not even funny.
