Their website is still unclear about the differences between "hobby" one-time licensing and "professional" flight plans - I hope they elaborate a lot more about what can and can't be done with the basic amateur/hobby version.
I thought it was pretty cool when in beta and I'd certainly consider paying $29 if it has those capabilities for automated mission planning.
What would REALLY impress me is the ability to plan missions in high-res detail on my big-screen Windows PC with mouse and keyboard, vs. trying to create a mission on a little tablet with just a touchscreen. I took at look at their updated website and didn't see that ability yet, although they mentioned during beta that it might appear after release, which just occurred - so I'm waiting patiently to see what evolves.
It seems like a good product and I hope the devs succeed with it. I think commercial users doing inspections could easily justify a license.
