What's irrational about disliking an environment hostile to developers? When you you do robotics, you want full control over the software, so the natural fit is some Linux variant, not OS X or iOS.

Hostile to FOSS developers you mean.

Many of us don't have any issues with comercial vendors.

Actually, I am the opinion all types of software should suffer the same legal penalties and quality control that other industries have in place.

I could say that far more about FOSS developers. Many of them operate under the idea that they bear no responsibility for the software they write, and as such, have no impetus toward quality.

Yeah, no. I've never bought the "hostile to developers" argument. Try again.

"When you you do robotics, you want full control over the software"

And OS X gives me this.

Maybe you don't realize that "software" includes the kernel. Is it even possible to do a real-time fork of it like people did with RTLinux, RTAI and Xenomai?

Of course it's not, because OS X gives you shit and you invested so much in it already that you have to convince yourself that it tastes good.
