What does a tablet do better than a laptop except for digital drawing?
I can share some specific examples based on my experiences as a teacher for well over a decade.
1) Teaching in class, my pdf documents are stored in notability. My iPad is mirrored to the Apple TV, which frees me up to walk around the class. Annotating on them is a breeze thanks to the Apple Pencil. The overall experience is so much better compared to windows where the UI is less optimised for touch.
Mobile apps also strike the right balance of simplicity and functionality for me. I use scanner pro to scan documents to pdf, lumafusion to edit videos, screen recording for screencasts, shortcuts and the camera app as a makeshift visualiser.
On the consumption side, I use overcast, Tweetbot, Apollo and a variety of reader apps.
I suppose a surface tablet could do them, but intel + windows have never really made for a great combination.
2) When I went overseas with my students and was tasked with blogging about the daily experiences, I brought only my iPad along. Again, the same benefits apply (thinner and lighter than a laptop, blogging was a breeze due to the native Wordpress app, inbuilt camera app, long battery life, inbuilt cellular, and the form factor lending itself particularly well to being used while on the move or on my lap on the bus).
3) When I am reviewing or reading documents while lounging on the bed or sofa (which is a large part of my work as a teacher), a tablet is so much more accessible than a laptop.
4) It's great for presentations as well.
The common advantages that have led me to continue working from the iPad this last decade are that the iPad is this perfect blend of battery life, ease of use and portability for me. Which I think is often overlooked amidst the discussion of what the iPad cannot do and how it needs more functionality. Complexity is not the key selling point of the iPad here. Simplicity is.
