I was considered 13” Onyx Boox Lumi Max, and still do, but couldn’t justify as I don’t do that much organized reading.

Onyx made annoying product decision to not include microSD to expensive 10 and 13 inch models, while still keeping it on 8” Leaf2 and Page.

Are you using written notes while reading on your Lumi Max or typing only?

With such reading system I would look into Obsidian/Notion/Readwise/Logseq/Tana running on Lumi Max - at least Obsidian and Logseq has android apps. Note that Logseq is local first system - it stores files on your disk then the option to sync on your server for free or their paid sync service.

The BOOX devices do come with an OTG port, and it's possible to attach a MicroSD card via that, though the arrangement is somewhat perilous (risking physical damage to the card, OTG attachment, and port) and not ideal.

I too would have preferred an integrated MicroSD slot. Current cards are available in 1TB+ sizes, which should satisfy even my prodigious appetite.

I do make use of handwritten notes as well, both in documents (Neoreader) and in the notetaking app. I've found that far more useful than I'd anticipated, though searching notes is of course challenging.
