That's great to hear. But since pretty much nobody here has access to those awespme internals, I still don't see where the gp's "really cheap" impression would be coming from.
When you have used the technology and seen with your own eyes the amount of time and effort it saves you when developing a mobile app, $85M really seems very cheap, especially when you compare it to how much they paid for an Instagram for example. Plus it should be mentioned that although their primary focus was on mobile platform, their SDK's also support Windows desktop, MacOSX, and traditional web dev. The potential is absolutely huge.
