I’m a Gemini user, use one almost every day when away from full size devices. Absolutely love it, it has filled a big usefulness gap and I would be without it. However, I chose not to back Cosmo because for my use, the only benefit over Gemini is the backlit keyboard. the negative is the Cosmo isn’t supported by Jolla for Sailfish. I dumped Android as soon as it was possible and I’m using paid license for Sailfish with the over the air updates, which for me is the big selling point of Gemini.
