My iPad Pro is my favourite portable device that I wouldn't want to give up. Definitely not a feeling I have about my Macbook nor my iPhone.
I felt the same way about my MacBook Air. It's been my constant companion since 2011 to a dozen countries and dozens more cities. Love that machine.
This past April my wife bought me an iPad. The last three trips I took were with the 'Pad instead of the Air. I'm really surprised how useful that little thing is.
I feel like I can go back to a feature phone now.
