I recently read the Bobiverse books, and those were quite fun.

Daniel Suarez is another good one (start with Daemon), as is Ian McDonald (Dervish House, the Luna series).

I find around the 8” mark to be the perfect tablet size. However, not a lot of good options out there, especially for more high end hardware. If money is not an issue, a foldable might do it?

Seconding this recommendation. We’re using one as a chartplotter on our sailboat, and it works great.
