Since the Pi Zero doesn't come with an Ethernet port, I'm wondering what is the cheapest way to get reasonably fast network connectivity to the device?
By "network connectivity" I mean connecting to a LAN/WLAN, so the devices can talk to each other, talk to other devices, and go to the Internet. E.g., after setup I should be able to
wget stackexchange.com. I don't actually care whether it's WiFi or Ethernet, but I'm guessing that Ethernet should be faster and more reliable (just a guess).
Someone just asked whether this could be done with HDMI, so I know other people are looking for a solution to the same (or a similar) problem.
