I can second that. Had the Gemini. Never used it much because everything was awkward about it, from the lack of software/firmware to the keyboard until two years later the battery expanded and was bending the case. Not only refused planetcomputers to replace it for free, the only option they gave me was paying £125.00 and sending it in. I've asked if they can send me a replacement battery so I can do it myself but they refused, pointing out safety issues with mailing a battery - while asking me to send the Gemini with the swollen battery to them.
