Any effort devoted to a mobile OR is effort taken away from other development, and I just don't see it as a useful allocation of resources. It was done once, and there wasn't enough interest to keep it going....and this is something that someone could theoretically do at the field, after first flight.
I don't comprehend why some folks are reflexively arguing against the idea of mobile OR. It would be nice to have. Of course it is possible to live without it, and it is not *essential*, but it would be nice. And if I had my druthers it would be full functionality. Fiddling with designs is fun, I'd love to be able to do it when I'm out and about and bored, or when I'm on vacation only with an iPad but not a proper computer.
I mean, it's not gonna happen any time soon, but why wouldn't we want it if we could get it?
If you want to do this stuff at the field, just bring a laptop.
