How many refrigerators do you think *one* manufacturer sells IN A YEAR (forget about next year)? How many irrigation controllers? Televisions? Dishwashers? etc. I've worked in industries where the saying was "you're paying for the plastic" (that the device is encapsulated in). You still find single-sided circuit boards in products. Multiple *cheap* processors where one "better" processor could suffice, etc. And, I'd wager a boat load of ASM where a HLL would be *so* much easier on those poor programmers... I've never met a manager who wouldn't try to figure out a way to cram some extra functionality into a product *or* trim a tiny bit of resource out of it -- when dealing with volume products. Your first offering may be "wasteful", but you quickly refine it to cut the waste out (get your foot in the door to get market share, then figure out how to boost profit and/or give yourself more margin to compete with other vendors on price) And, time spent *now* can be leveraged in future product designs. Save a penny now and you've also saved it tomorrow. > For a lot of applications, preposterously cheap horsepower has > outstripped our ability to use it all up.

Why don't we see 32b processors in mice? Hell, think of how many cheaper programmers you can hire if you can code the application in Python and run it on a 100MHz CPU! Look at all the time those programmers can then spend sleeping! :> Why isn't ethernet connectivity *more* common? Heck, you've got all those resources just sitting there! Add a PHY and a connector (or, a radio, etc.) When you're buying them by the millions, everything is *free*! The next generation of parts can have the PHY and connector *on* the silicon! :-/
