It was already discussed at the beginning of this thread when the question of the OS(es) was still open, but again I think it's a very sound decision. Your recent comments about the number of secured tablet sales and the mimimum batch size required to run production only emphasize how important it is to reach a community beyond ours, even if Maemians/Meegonians are obviously and objectively far superior to mere androids (!).

Even if the device is 99% an Android device and everyone on Earth considers it an "Android revolution" despite its roots here, there'll be no happier community than ours with 1% of units running Sailfish or another alternative. If you make it possible by opening the bootloader and actively supporting an official Sailfish port or community ports (hopefully with Sfdroid or Anbox, since Android compatiblity layer is really important in 2017, as sad as it can be), that's already a huge progress. A huge progress none of us really thought would be ever possible.

Hope Android sales and preorders will be good after proven success of the Moto Mod and Youyota tablet, as a mean to make our little dream come true.
