Sailfish, itself, is free. If you get a phone that's supported as part of Sony's Open Devices Program: https://developer.sonymobile.com/open-devices/list-of-devices-and-resources/ https://developer.sonymobile.com/open-devices/list-of-device... , you may be able to use it with both Sailfish and Android. Although, I expect that support for the more fancy components on the newest phones will take longest to arrive in Sailfish.
