Changes

Raspberry Pis do not have onboard storage (except for the Compute Module), and they do not have onboard WiFi or Bluetooth(excepting the B 3).All Pis (except for the Compute Module) support 3.5mm audio out (poor quality, but useable), HDMI out supporting 1080p30, and composite SD video out. Some also support I2S audio out.All Pis feature the VideoCore IV GPU, which is fairly powerful given the rest of the components. It's roughly as powerful as the GPU in the iPhone 4s.
