I'm planning to spend a little time making a basic port of Android to the Jolla1, as I have serial cables, access to a lot of stuff, etc..

The reason I'd do it is not to betray SailfishOS, naturally, but even for a lot of experiments a simple Android build helps a lot to put whatever you're want on top. Or people can see if they can get 4.4 or 5.0 working, for getting a better SailfishOS HADK support on top.
