What about the Remarkable ( https://remarkable.com/ )? It's both got a larger screen and it's supposed to have a vastly improved refresh rate. I haven't tried it, but I'm really really curious about it.
It's beautiful hardware matched with absolutely horrid software. It's Android 4.0, which means literally nothing works. They've tried to fix it with custom apps, but I still can't achieve a decent work-flow and there's no community to make it better. It's actually the worst.

I use the remarkable for taking notes on online courses, and works wonders.
