Re: I threw some money at this....
Battery life is appalling. The cover display burns as much power as the main board. Seeing as the cover display is supposed to be the killer feature of the device, then switching it off turns it into a slightly improved Gemini.
Even with the cover display off, you can watch the battery level drop when using it. They seriously messed up a promised update that was supposed to improve battery life and we're still waiting for Planet to release a fixed version.
Now they have launched another Kickstarter campaign for a new device before fixing the current device issues (the new device is notably dropping the cover display idea. So they have obviously realised it's a bad idea).
Same old story as the Gemini.
