My main note taking device. For anything serious, I go to my MacBook Pro 15", for its larger screen, and mouse support.
What I like about a tablet/iPad:
Can casually bring to meetings
Less serious than a laptop
Because I can do less on the iPad, it forces me to focus
The lack of good multi-tasking is a positive for me. I get less distracted.
Wants:
Apple Health app for iPad
I want to be able to view my Apple Health information on my iPad
iPad Pro 11" 2018 vs iPad Pro 10.9" 2017
Overall: It's still an iPad
Pro:
I like the USB-C, "universal" charger everywhere
Larger screen
Apple case protects the full iPad
iPad Pro 12.9" 2017
I used to own the larger iPad Pro 12.9" 2017 model. It's big. It feels like a great laptop replacement, but it's big and not entirely practical to carry around with me everywhere, hence why I like the smaller model.
