Raspberry Pi vs Gumstix

I have received Gumstix Robovero to play around with. On top of from the picture is Raspberry Pi B and from Gumstix Robovero at the bottom.

ImageWith a RoboVero featuring a standalone ARM® Cortex™-M3 driven LPC1769 microcontroller and a Wifi/Bluetooth-enabled Overo AirSTORM computer-on-module running Ubuntu with Robot Operating System (ROS), the Gumstix Robotics Development Kit makes it quick and easy to get started on your robotics project. Featuring many header pins and the ability to drive the microcontroller independently via a HubCommander™ interface, the Robotics Development Kit is ideal for motor control applications.
