We have a competitor for the high end of the electronic flight bag market, we call it ADSBee Winglet: https://pantsforbirds.com/product/adsbee-winglet/

We're focusing on embedded applications with ADSBee m1421 applications right now but it's definitely tempting to roll m1421 into a smaller flight bag device. It's something we might get back around to once we have Winglet off the ground.
