The Snickerdoodle got a lot of attention for its price point (which turned out to be unrealistically low... I commend them for following through though). It's an odd platform. They were going for an ecosystem of carrier boards, but ended up with 0.050" pitch connectors. Which are good if you've got flying leads, but I can't see myself using a Zynq for that kind of work. The mating connectors are ~$7 in small quantities which is comparable to the smaller, tighter pitch connectors other dev boards use, so there isn't really a cost savings if you build your own plug-in boards. It might even cost more for wide I/O in terms of connectors and board space. You're right that technology has continued to march along. $250 for a Zynq Ultrascale is very tempting, but I have enough dev boards collecting dust...
