Analog is hard, and quite different from digital.* And then you have to work around the patent thicket in an already difficult domain. * Nowadays clock speeds are so fast that you have a lot of analog things to worry about with all these high speed serial lines and on the chips themselves. But the domain constraints are in general simpler, with recovery and reconstruction opportunities available due to things like how you structure your protocols. The same is true in radio (came from radio, actually) but when you have a device operating at arbitrary and continually changing orientations, with all sorts of unknown environments outside you get all sorts of unpredictable multipath, loss, ringing and innumerable other problems to deal with. |

In the infamous words of Bob Widlar [0]: "Every idiot can count to one."
[0] For those who don't recognise the name, Widlar was a legendary analog designer - along with Jim Williams and Bob Pease.
