Not the hardware, the apparently wide-spread perception that the cRio is too slow has little to do with reality.
And this has nothing to do with LabView -- I'm staying out of that debate from now on.
I'm perfectly happy with the cRio and vxWorks.
But the (C++) software is too brittle; and too opaque to diagnose and trouble-shoot.
I'm not a big fan of Linux for embedded systems, but I think Mike has started something here that has value.
The kids who want to learn software are just learning shotgun diagnostics.
They should be taught more methodical and analytical approaches.
I hope you are not offended, I am blunt when I think bluntness is called for.
I would be happy to take this discussion to email if you think that's worthwhile -- please PM me if you do.
