Do a Google search on Nomadio, you will see where there have focused their efforts:

I don't see Nomadio in the hobby business much longer, what they've done to their hobby customers is really pathetic. Guys like 46U chose Nomadio because of the technology, they took a chance on Nomadio's support and got burned. Sure it's awesome technology but what good is it when there's no firmware updates and you can't get sensors or receivers easily. If you don't think Spektrum or Futaba doesn't have the technology to provide USB support think again... they do but they know that providing access to the radio's firmware would be a logistical nightmare for their support teams.
Thank God for my Futaba 3PKS, even as it nears discontinuation it is still one of the best radios ever made. I like it so much I bought a second one !
