I'd buy an iPad Pro tomorrow if it ran OS X. In its current incarnation I just don't get it. It's simply a big iPad.
The iPad Pro did not replace my Macbook Pro, but I can use it to do almost everything I use my Macbook or iMac for. For some of these tasks, the iPad Pro actually does it better, because of the pen and/or portability:
(for work)
- reading journal article in pdf, and annotation them with inking (and share the files with annotation with all Mac and Win users), the big screen also mean viewing the article at full page without needing to zoom in
- taking notes and/or lecturing with inking over Microsoft Office, especially for scientific/mathematical equations
- note taking in seminar using the pencil, especially when you arrived late and was standing at the back of the room
- light editing of photos, such as outlining the focus and blurring the background, enhancing the color
- in round-table discussion, sharing content simply by laying down the big iPad screen on the table
- did I mention inking in Microsoft Office suite is enabled for the first time in the entire Mac OS/iOS platform?
(for fun)
- huge selection of iOS games
- catching up with e-magazines, or news using Flipboard or similar news apps
- watching movies, especially in situation like: sharing with two or three people sitting close to you, not having to be interrupted when your plane is landing because the laptops have to be stowed away
