It's hard to look at the pi zero and not consider the advertised price as the major feature (a few will benefit from the size, but most of the discussion seems to be about the resulting limitation, rather than what the size might enable).
If that price isn't a reality for people in some markets, then in effect the board isn't a reality either.
One could argue that price issues will be transitory; but then so may well be the position of that particular board relative to its potential alternatives. In particular, it is hard to note the time proximity of the pi zero's announcement to the impending release of another ultra-low-price Embedded Linux board and not wonder if there is some market/attention jostling going on. It's also quite likely that none of the current offerings from any of the vendors (pi or otherwise) will turn out to be quite what they could have been (still, with the SD card, still, with the blobs, still using a chip you can't realistically buy), a situation which will hopeful improve with time either within product lines or across them.
Normally, SE sites try to steer clear of things like pricing of specific products, however with the concept of this site being (for better or worse) tied to a specific product line, that is much less avoidable than it would be on a site covering a concept which has multiple competing implementations.
