Memory footprint is still an issue in lots of things like ESP8266 (which doesn’t yet support IPv6, but hopefully will soon).
Not everything is a cell phone or larger. There are lots of cool new things coming out in the SoC world where you’ve got a micro controller, GPIOs, CAN, SPI, WiFi, and more all in a single chip or module. Another example (also currently IPv4 only, but hopefully that will get fixed) is particle.io. These are $10-$20 (and sometimes even less) complete systems with very small memories and very low power consumption which are great for deploying things like remote sensors and the like.
