Ehm, a Pixel 9a is currently 349 Euro here (10a 399 Euro). Given that the OS is free, that's only a 19 Euro difference. For a much better camera, much better SoC, much better pretty much everything.

Of course, if your goal is to run SailfishOS, there is currently not much of another option.

It's pretty cool looking! Very optimistic about it.

The Pixel 10a is on sale for $399 on Amazon right now, and it's a far better device, and it can run GrapheneOS.
