I think a distinction can be drawn between the Arduino and the Raspberry Pi. I can see a use case for a (relatively) cheap, easy to program microcontroller with a board layout that makes it dead simple to integrate with sensors, motors, actuators, switches, etc. But that's an Arduino, not a Raspberry Pi. A Raspberry Pi is a small ARM SoC that tries to be both a microcontroller and a general purpose computer and doesn't do either particularly well.

What about when you want to get those motors, switches, actuators, etc. accessible over the internet? Linux-based boards are fantastic for this use. There are options to get an AVR or similar 8-bit micro onto a network, but if you do anything non-trivial (like parsing web service responses, trying to communicate over SSL, etc.) you will quickly hit the resource limits of the processors. Linux + realtime microprocessor is a really great combo. Right now the Beaglebone Black and Arduino Yun are some options, but it would be nice to see more.
