I once walked into the Arduino IRC and asked if it could run maxima. The response was that I'd be lucky to get it to run Linux. The arduino costs more than $25. Everything you listed there costs more than the utility value it has for most people.
For $25 a pop you can do innovative prototypes on the kids-allowance cheap. The size is an extra bonus. There is no end to the number of ~$50 projects I've thought up that consist of a pi and peripherals. To say that those other projects you mention are somehow comparable is ridiculous. They all cost multiples more money than the pi.
The pi is really going to speak to my demographic: Teens in their basement who have no money to spend on flashy prototyping equipment. But have tons of ideas they want to try out.
EDIT: And continuing, for doing a "production run" having multiples lower production costs is a serious advantage for cash strapped endeavors. Not sure if the pi foundation will let you order enough to do that though.
