Just curious, but if you enjoy a Nokia N900, would you not consider the Cosmo Communicator or the Fxtec a good follow-up? It has modern hardware, still a good hardware keyboard. Together with the more updated Sailfish OS you get something much newer and faster.
I can imagine criticism about Jolla not having everything open sourced, but what I remember it was the same situation with Nokia for the N900 and N9. Also, in some respects the UI of Sailfish is somewhat different from Maemo/Meego, not everybody will like that.
Is the keyboard really good? I’ve tried one of Cosmo, Gemini, or Fxtec in person, can’t remember which, and utterly disappointed upon first touch. It looked like a proper laptop but keys tilted on roll and pitch axes like a TV remote. Good hardware keyboard seems to need a lot of iteration and investments to do so.
