Also the hardware support for common devices lacks in vxWorks compared to Linux.

That's for darned sure. Their USB stack blows, for example--things that Just Work on Linux (which is lots and lots of things) require weeks or months of support calls and workarounds with VxWorks.

But Linux will not obtain the low interrupt and task latencies of vxWorks. Linux will probably get to 50-100 us whereas vxWorks is down to 1-10 us on a typical embedded target.

It won't come close to hitting VxWorks' footprint, either. But that's OK--they're different OSes with different markets (i.e., target hardware). Wind River's problem is that the market for the minimalist hardware on which VxWorks shines is rapidly vanishing.
