Arduino in the size of a AA battery
Great form-factor to easily re-use existing battery enclosure, but I have been wondering lately about the long-term future of arduino.<p>With the low price of something like the Pi Zero which is running a full version of linux, or something like the Esp8266 which can run many different languages, you're basically paying shipping costs. What benefit does arduino have in this future, other than a large existing network, which I understand can't be overlooked as a strength.
