Hi As a free time proof of the capabilities and responsiveness of the Balloon I decided to port Android OS (http://en.wikipedia.org/wiki/Google_Android) onto a Balloon development board. Below is a youtube video link showing the results, a Balloon 3 running Android with a Toppoly 480x640 resistive touchscreen & CUED breakout board usb (via hub) to keyboard and modem (Siemens MC55i module). http://www.youtube.com/watch?v=YkOl6xyAHr8 Apologies for the varying light levels & lack of resolution/audio. Note also the webpages were in the cache from a previous test run, GPRS isn't usually that quick.
