This seems like the perfect place to talk a little about the latest hype in open technology that is the Raspberry Pi: It's minimalist, it's technology, it's super cost-efficient. I'm not a sales person by the way. I'm just genuinely intrigued by this idea.
And the idea is that for $25 you can get a credit-card sized computer (without a hull) operating on a Linux system with 256MB RAM and as much storage as the SD-card you give it. It's meant for schools to teach programming, but there are lot's of people getting one and building cool stuff with it. Just look around on youtube.
It even automatically starts an apache web server on boot. You can use it as a super minimalist web server - and it seems like it was made for evented programming like node.js as it supports a single execution thread very well. Also it has a lot of I/O pins that you could use for example to remote control all kinds of machinery with it.
