Rasp is explicitly mentioned in the OP. Why don't I just use a Raspberry Pi? The Raspberry Pi is a fantastic product, but it is built with an emphasis on education and 'home hacking'. It lacks certain features found in the Ocean. Raspberry Pis do not have built-in Bluetooth or Wifi, and do not come with an on-board power source. While you can purchase cases for them, these cases are rarely designed with portability in mind. Exposed GPIO pins tend to bend in your pocket. A Raspi can be augmented with additional hardware to equal the feature set of the Ocean, but this hardware will compromise the portability of the Pi.
