we've got nothing in common; no common ground to start from..

Oh, wait. Wrong thread.

... that you've worked with VxWorks, and blah blah...

But, have you just programmed with it?

Or have you negotiated the multi-hundred-thousand unit sales contracts, which may include bundled programmer support which a vendor shipping Linux would likely have to either expense internally or pay someone outside for?

You can't bundle support into free.

Right, there are some hidden costs when using Linux, but the same goes to VxWorks based system(s).

You still have to spend time to port the BSP codes, and you still have to spend time test the protocols, fine tune. Overhead for running automated tests on VxWorks is too much for a small system, but may be ok for larger systems. But then again, on large systems, memory isnt a issue, so use Linux not VxWorks.

Linux is just easier to work with compare to VxWorks.
Yeah, in general VxWorks takes less foot print. But I have to mention it is really annoying to have to reinitialize the VxWorks based systems we have *every time* we make a minor configuration change. For what it is worth, choose Nucleus over VxWorks in a peer to peer comparism.

Their licensing cost isnt cheap either. Might as well take the money and increase your memory size.
