Paul, I am a systems engineer and software developer. I specialize in device drivers and interfaces. I am also an amateur astronomer with an interest in astrophotography. I plan to write drivers and interfaces for the Edge that would allow it to control my astronomy gear. There is also a planetarium software that I will attempt to port so that it would run on the Edge.
Before that can happen, though, we need to get the device. Has anyone obtained a definite answer as to when the Edge will start shipping?
