"Isn't your small laptop a more powerful system?" EeePC with win. Now I could fire up the beastly server I have on my desk with 300W power supply, multiple HD's with linux, but as an experiment I moved all the dev over to a Pi. Add a few more Pi machines and I can use one for image processing, another for dev, another for sound/media & I have the core of what I used to do on a desktop for the price of a fast HD.
