Pixel is supported until June 2028.

Palma is running a closed fork of Linux with non-upstream drivers, https://old.reddit.com/r/Onyx_Boox/comments/1btqzoa/palma_is...

  - Palma was released at August, 2023.
  - It's operating system was Android 11
  - 05 Feb 2024 security supports was ended for Android 11

  If you compare these dates: August, 2023 and 05 Feb 2024. It is only 7 months of lifetime - between release and end of security support.. Somebody in Onyx decided to use Android 11 instead of 13 that was released 15 Aug 2022 - 1 year before Palma release. 

Small size and e-ink screen.. for 7 months.
