Emacs are like Russian literature. They are rich in substance and offer timeless value. But it is often hard to get into - and more of an acquired taste.You're right. It's not worth most people's time. I just happen to use emacs.
By the way, you can combine evil mode and org mode in an SSH session on iPad if you want to try a mobile interface.

If I bought a single board computer for wake on lan functionality and VPN, I would be able to connect from a tablet to my desktop computer over SSH. You can use a bluetooth keyboard with a tablet or a laptop.
I can use org-mode over SSH on a tablet. evil-org-mode enables vim keys on emacs. VIM keys are suitable for SSH sessions.
If you want to work offline, you may set up a folder synchronization system so that when you get home, your org-mode files are automatically synchronized.
