I'm not a programmer or a hardware hacker. I don't know anything about soldering circuit boards. I'm just a guy who likes to surf the net, write stories, play games, hang out on-line, and so on. What is the availability of this $15 device going to mean for me?
I mean, at least (as far as) I know the Raspberry Pi is going to be producing fully-realized devices that I can buy, plug in a keyboard and monitor and Ethernet cable, and I'm done. It sounds like this project is just about building a circuit board. And while it's nice it will be 40% cheaper and three times as fast, I'd like to know what I could do with it if someone came up to me on the street and handed me one.
