Fraser Speirs spins the question of whether the new iPad Pro can replace your laptop 180 degrees: Can the MacBook do what the iPad Pro can? Framed this way, it seems crazy to pick a MacBook over the iPad Pro.
It would be easy to say the tech reviewers simply went for the easy angle of comparing the iPad Pro either the iPad Air or the MacBook, but I think that misses the point. Horace Dediu of Asymco.com got it right, the iPad Pro is something new. We need to allow it to be something new. It feels extravagant to say we might want an iPad Pro in addition to an iPad or MacBook. There can be only one portable device. Why? We don't seem to have any problem having a laptop and a desktop. We can also have a laptop and an iPad. What is so wrong about having a laptop, an iPad, and an iPad Pro?
I don't have an iPad Pro yet. I haven't even seen one in person. I do anticipate that there are lots of things I could do with one. Useful things, both for entertainment and for actual work. I walk around with my iPad Air one handed as I'm reading articles (or more likely playing games, listening to podcasts) while I'm doing laps in my house getting steps. I'm not sure I could do that with an iPad Pro due to the size and the weight. I'm not sure I would want to give that up if I had an iPad Pro. I wouldn't feel bad about that because I would use the devices for different purposes. How many one-function tools does a wood maker have because certain jobs can only be done with that one unique tool?
Often the easiest way to understand what a thing is is to compare it to something else. That's fine, but we just have to leave room for the fact that a new thing might actually be new and thus alien. It may take some time to actually understand what it is instead of just what it looks like. We need to be open to the fact that a new thing might create new workflows instead of just replacing existing ones.
