I don't see anything about Ethernet/Wi-Fi. Am I missing something?

I understand they had to cut some features to reduce the prize. But networking is such a fundamental requirement for these types of systems, you'd think that it would be the last feature to be excluded.

There's a USB port.

This is seriously impressive.

While the Raspberry Pi is not the perfect hacker-friendly computer, it has done a lot of good. Some reasons off the top of my head:

1. Providing a low cost computer has given many people access to computers. Giving more people access to the web, email, an office suit, a programming environment AND giving people the ability of safely tinker without the fear of bricking an expensive device.

2. Introduced many different types of people to the FOSS landscape of powerful tools (e.g. distros such as Debian, tools such as Python).

3. The Raspberry Pi foundation has paid developers to write/optimise FOSS (e.g. paid Collabora to optimise WebkitGTK+ -- I think some Wayland work was also done).

4. Built on top of existing FOSS tools (e.g. building Raspbian on top of Debian), instead of doing everything on their own in a proprietary fashion. This has no doubt also helped to introduce new people into these communities.

This is a really good counter-point to all the "locked down" (hacker unfriendly) devices like smart phones and tablets.

The networking on the other Pis is attached via USB. It's a very easy and obvious thing to drop.

This is intriguing. Is there a list somewhere that shows the cheapest possible place to get raspberry hardware modules. Also, where do you guys buy your modules? You can include Arduino stuff.

I just use eBay for Arduino stuff. It's a bit more expensive than AliExpress but I suppose I get a bit more buyer protection. This screen* is pretty cheap, right? I'm currently using one (on an Arduino, different seller) and it works great. * http://www.ebay.co.uk/itm/2004-204-20x4-Character-LCD-Displa...

That's really cheap compared to where I got mine along time ago. Very Cool!

To what degree are the power requirements on their faq still valid for the pi zero ? https://www.raspberrypi.org/help/faqs/#power The question I really want to ask is, how long will a 1.2A supply last with nothing else attached to it ?

Your question isn't meaningful, because amps are a measure of the rate at which a power supply can provide current.

An AA battery can provide 1.2A for maybe an hour or two; a wall wart can provide 1.2A indefinitely.

Plug a wipi into it via the USB OTG cable. Done.
