Memory footprint is still an issue in lots of things like ESP8266 (which =
doesn=E2=80=99t 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=E2=80=99ve 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.
