It's also not really a $5USD computer if you need to access it in any way. Add mini-HDMI to HDMI via cable or adapter if you want to see anything, plus the keyboard/mouse. Or if you instead want to go headless, you need either a microUSB to network solution, or solder on header pins and access it serially / via GPIO. (I guess you could go the Gadget approach, but that has its own overhead.) When you add in the accessories that are required to actually make the $5USD Zero functional you're very close to just moving up to the full models and those are in stock everywhere and in quantities now.
Well....maybe. Some things that are needed to support a Pi Zero are also needed to support other models. The only support item unique to the Pi Zero is really an OTG cable, and that isn't needed for all uses. If you need header pins, then those have to be purchased, but ther eare some source that put that cost down at the noise level..that is, less than $0.25, which is hardly going to bump you to the cost of an A+. Eve if you go expensive (e.g. Adafruit) a 2x20 header is still less than $2.
I agree that whether or not a Pi Zero makes sense is very project (and person) dependent. I'm working on one that could be done with an A+, butI've chosen to do it with a Pi Zero. I would need a short USB cable (power), the battery, and the display either way. For the Pi Zero I'm adding the header and an OTG cable, so less than $4 additions with a Pi Zero that I wouldn't need for a $20 A+.
It doesn't hurt that, at the moment, Pi Zeros are actually easier to get than A+ boards.
