Yeah, I flew with EDM's in the sandbox. The 60S wasn't the right airframe for them, the cords were so short pilot's couldn't use them so we had to rely on the aircrewman in the back to relay information to us. So, we couldn't use them for charts/maps very effectively... our crewman got pretty good at talking us on to the BLUE forces with it. It was a good back-up to secure comms. When I went over the orizon and SATCOM was acting up, a quick textmessage back to base was always useful.We use those too; I thought they were owned by Raytheon now. The hardware updates have gone a long way to making it faster and more responsive, but the interface is still from the 1990's (stylus on top of Windows) and needs to be brought up to modern touch interface conventions.
I wish the EDM was in more general use, only having it in Iraq and not elsewhere is dumb. Also, wish the pilot could utilize it, as that's what it was designed for. The few times I did mess with it, it is a clunky old piece of software, ripe with bugs and glitches... and had like a 10 minute boot-up time.
