I think those counterpoints to the example are being a bit literal. I too have a "fancy" DSLR and I definitely consider the sportscar analogy accurate. I think the heart of the analogy is different from what you're giving as examples though. To me it means that there are places where you do want to use the sportscar, and places you don't. I rarely use my DSLR - why? Because I'm usually "commuting" and it's just too bulky for a daily driver. My commuter car fits in my pocket, and is always with me. Talking about how special places are designed for the sports cars and inferring that it can/should only be used there seems to me incorrect inference of the analogy. At that point we may as well talk about expensive tire repair and maintenance, but I don't think that was intended either haha.
