One of the cool things about arduino lately is that they're getting cheap enough and small enough to just use as part of finished projects, instead of just as learning tools or prototypes. The neat thing about raspberry pi was that it offered a similar proposition, except instead of a microcontroller you could bring to bear the full power of a computer running linux. I'm more excited to see smaller, lower power, and cheaper versions of the pi than more powerful and more expensive versions. Because that's what will result in them being used in projects more.
