Capturing market share for a company as small as Laminar, even in the void left after the demise of FSX and Flight, was never going to be an easy task. I've never been an FS user and can only go on the observations of the many friends of mine who are, but their opinion is that while they are impressed with what X-Plane has to offer and would be all for adopting it, they simply can't afford to jump platform having already invested years and hundreds or thousands of euro in payware add-ons and have to start again from scratch. And now with Prepar3D on the scene, they see that as their way forward. (Although most will be content to stick with FSX for some time yet.)
