- check my emails;

- manage my todo lists (previously with Wunderlist, now with Microsoft To-Do);

I make liberal use of the window snapping feature to do most of those things side-by-side with my browser open.

When in tablet mode I'm primary consuming content, and I've found that my Windows device is just as good at that as an iPad or Android tablet. If I'm in tablet mode I'm sticking to the apps that were built for touch, i.e. apps from the store and Edge, not poking around in VSCode or other apps meant for a mouse or keyboard.

What really sold it for me was that I can just flip it over into full laptop mode whenever I want and have 16gb, core i7 dev laptop ready to go instantly.

For reading PDFs, I'd recommend taking a look at Edge again. It's pretty great for reading PDFs and ebooks with the new Creator's Update.

Already does fluent design (acrylic) and is very actively supported. Just days ago it added 360 support for example which I think no other app does. It's really good.
