Batch 1 ‘Aspen’ handsets — all of the batches are codenamed after trees, alphabetically, from A to F — provide a usable phone with complete initial board and all hardware components included.

The case, however, will be handcrafted and, Purism say, may have a “loose fit” and variation in alignment, as well as unfinished kill-switch caps.

Software-wise things won’t be super smart, app updates will need to be installed via the command line, and, more ominously, the device will tout “early power management”.

Batch 2 ‘Birch’ follows a month later (October 29th – November 26th) with all of Aspen’s features but a tighter fitting case, improved software, better power management.

Batch 3 ‘Chestnut’ ships in December with all of the above, plus capped kill switches, “final setup”, and much improved power management.

Batch ‘4’ Dogwood (January to March 2020) adds improved core apps, third-party apps, and a refined GUI app store

Batch 5 ‘Evergreen‘ features a moulded case.

Finally, there’s Batch 6 ‘Fir’ which boasts a 14nm Next Generation CPU, revised mechanical design, and long-term support release software.
