If you were a programmer, it seems like the RPi would be a better choice than the arduino -- you can code in the language of your choice instead of processing or C, and you can still control interface pins to the outside world. Also, you'd probably do more with the Pi as a programmer beyond turning pins on/off -- for example, you could hook up a camera and run opencv, then write a small app to control a water gun that shoots squirrels off your bird feeding post. When you start doing more with arduino, you typically want network connectivity, and most of the wifi/ethernet shields for the arduino are the cost of the entire RPi computer. I think the RPi does fill a good niche in the hardware world.
