I think the author describes my point of view and defuses many of his own points at the very bottom of the page: also, you are likely making one circuit, not planning on mass-producing 1,000,000,000 of whatever it is; who cares if you spend a buck where a dime might do? you want it to work first time every time, right? this is art not technology (eg. industrial capitalism); we have different design criteria here. That's exactly right. I'm usually making one circuit, and not mass-producing them. My inefficiencies will likely be limited in scale to no more than cents per month on the electricity bill. If I were mass-producing, then of course I'll reach for the low-power switching FETs.
