Depends on what you're doing. I have both a 10.5" iPad Pro (with Smart Keyboard) and a 12" MacBook.Nope,
My next computer will definitely be a computer and probably won't be an Apple product with the direction they are going.
Content consumerism vs creating content. I do useful things with my computers, life isn't entirely about the 'hubs!
The iPad Pro is much, much better for content consumption.
For content creation, the MacBook is better for some stuff, but the iPad Pro is better for other stuff.
Overall, I use the iPad Pro much more than the MacBook. I won't be buying another MacBook, but I will definitely be buying another iPad Pro.
