Planet's after sales support is, unfortunately, very poor. It's not for want of trying but they are just not set up for it.
I have one of the early Gemini's and had to replace the keymat because the spacebar wasn't reliable. Unfortunately a couple of the keys were damaged during the replacement, which you have to do yourself. I prefer to have a German keyboard and have been waiting for one since July. I was due to be sent a set UK keys but looks like I was sent US instead: nothing comes with a delivery note.
I couldn't do the recent OTA upgrade so had to do another manaul flash. Everything is usable and a friend of mine is using the Gemini as his main device. Like others, the hinge on mine is working loose. I suspect that a normal company would have simply replaced the device by now as the first batch was know to have problems.
I can understand why they want to push on with new models, but I think they will fail if they do not improve support significantly. The people I know who need devices like these won't mind spending a bit more for reliability.
