Re: Raspberry Pi
This is what I find interesting about the Raspberry Pi:

What do you do with an ultra-portable computer that can be hooked up to any USB device, any basic input/output such as sensors or motors, and can be powered from one of those mobile phone backup batteries? Autonomous robots springs to my mind immediately. So do wearable computers. Others have had cooler ideas. Many more have had more mundane ideas such as "tiny noiseless home server" or "kids can learn programming with GPIO with a machine they can bring to school" but that's still cool.
If you just want a computer to write programs on, or use for web browsing and Facebook, you could pick up a second-hand machine for $35 the lot. Add $20 for a GPIO interface that plugs in via USB if you want to get into that.
Raspberry Pi, however, has a killer combination of features that makes it so much more flexible than your big, power-hungry dumpster PC.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
