I downloaded their demos. The calculator app looks impressive, but I couldn't get the G-code editor to run. It uses Adobe products, and after several house of troubleshooting and checking drivers, adobe issues, etc I finally gave up on it. Did you go ahead with the purchase? if so what do you think of it? Do you think this is something one would use after they gain some experience or is it just a learning aid that would get tossed aside later?
