Dave, this is no more OT than the original thread was. I love distributed control but it seems to me the sub-USD100 Intel Atom-based integrated motherboards have sucked the air out of the room. They're good enough and cheap enough. It's almost embarrassing for me to have become such a stick-in-the-mud. From the time I was a teenager, I was the one constantly pressing for innovative technical solutions. It took a long time to realize that our "if we build it they will come" projects often resulted in "we built it but nobody came (so we wrote a report!)". I used to believe our problem was that others were afraid of change. In my dotage, I've come to realize that we didn't provide adequate reason for others to change. From my admittedly biased perspective, the best argument for this distributed-functionality approach is the need to future-proof ourselves against the decline and fall of the traditional PC based on the x86-architecture. (which, like the news of the death of Mark Twain, is greatly exaggerated but not inevitable).
