That's great, recently I ported Redis to the Pi, and the most exciting device for IoT applications looked to be definitely the Pi zero, but the lack of built-in wireless networking was a big limit. At the same time the doubled price tag of the "W" version does not easily allow to use the zero directly as a building block of certain IoT devices or consumer products. What I hope is they'll be able to retain the features and lower the price at the same time.
