 AVR's have loads of great built in hardware e.g. I2C, SPI, multiple UART's , wake on interrupt, external ram busses ect. They are also a lot less power hungry than gumstix or routers, a typical AVR clocked at 16MHz will run off 3.3 volts at 25ma.  AVR's have loads of great built in hardware e.g. I2C, SPI, multiple UART's , wake on interrupt, external ram busses ect.

 + Not really a smart phone but more a smart phone module, but as it has a python interpreter,​ camera interface, GPS, GPRS with TCP/IP and analogue inputs this could run a whole payload!

 +
 + The python code has access to virtual terminals to control the phone and recieve data from the GPS (sirf3). There are also libraries for running bit banged i2c and spi out of the GPIO pins. 1.5Mb of ram avaliable. ​
