No, I don't know that. It is hard to "know" something that is not true. > Until you get to the level of sophistication of > an iPhone. Although Apple is getting much hype about the sophistication of the iPhone, we've been shipping convergent devices of that complexity for some time now. Apple have better industrial design, but they're not doing anything, other than the touch screen, that we haven't already done. You are now *starting* to understand the level of complexity of CE embedded devices. > My interest is in large scale systems, OF COURSE I'm=20 > approaching the problem from the point of view > of large scale systems and not small > scale systems. Don't be silly. Actually, Matt, it's you, by trying to solve a complex embedded systems problem as if it were a 'degenerate' large scale systems problem, who are "being silly." You keep handing me crowbars when I need a scapel.
