I backed the Planet Computers Gemini on Indiegogo and having used it for a few months I'm not quite sure what I think of it. I love having a physical keyboard, which is what this device is all about. I don't like Android, so waiting to see what Jolla bring with sailfish in the coming months. Things have moved on so far since I used a Psion 5MX back in the day, but this device form factor does still make sense to me. It complements rather than replaces my iphone.
For posting here, it's great to have this keyboard... But, I do feel the keyboard needs a little more work. There's a nack to typing quickly on it. Most of the time I get it but there are still missed keypresses as the key tilts rather than presses. But, it's a cracking piece of kit for a small company's first crowd funded product.
