Why throw away years of effort that has produced a VERY powerful and flexible framework that WORKS? Is there a real time patch set for that "single board" Linux machine? Without that, it is worthless for our purposes. Why need TWO computers, when one works fine? Think of all the debugging and logging hassles when you don't have hard drives on these computers, which would be the case on many of the single board embedded systems.
I certainly don't see the need for a move in this direction, yet. Maybe, in the future, desktop PCs will be so horribly encrusted with bluetooth and other wireless "crap", variable CPU speed, battery and thermal management that they will be forever unable to do anything in real time. We may have to develop a hardware compatability list of our own, testing specific models for RT performance, parallel port compatability, etc. I can recommend a few models myself, I've been using off-lease Dell Optiplex boxes with good results.
