Depends on what you mean by "tinkering". I had been on the lookout for a large Ereader from the very early days (i love reading books) and had owned a IRex Iliad and Nexus 10. I was looking for at least an A4 size screen (a must for reading technical papers/books) and finally settled on the Samsung Galaxy Tab S9 Ultra (14.6 inch screen) which i bought this year. I have the Moon Reader Pro+ as my ereader app and with the S Pen you have note-taking capabilities too. Add a bluetooth keyboard/mouse and you have a easy to carry "laptop/tablet/note-taking ereader" for many usecases.
