- The X3/X4 use an ESP32-C3 with no PSRAM, giving developers less memory than 1980s home computers

- Commenters note Xteink sells identical hardware through different channels with different software configurations (locked vs. unlockable)
- A commenter suggests packaging the project as a Crosspoint plugin rather than a standalone firmware to avoid repeated reflashing
