Google App Inventor for Android

Im keeping a keen eye out on mobile devices software that have some educational potential and functionality that relate to the science and technology disciplines and could be made freely available to students. Google have now released an application 'inventor' for its android based phones. Its esentially a way to write your own 'Apps' without actually getting involved with the nitty gritty of hard core programming. Its very much a visual programming language. I think their video says it all, with a basic example.

For me the bit Im excited about is that to quote Google:

"...App Inventor provides access to a GPS-location sensor, you can build apps that know where you are. You can build an app to help you remember where you parked your car, an app that shows the location of your friends or colleagues at a concert or conference, or your own custom tour app of your school, workplace, or a museum."

A piece of free software that allows access to the GPS is good news for field work as far as Im concerned. It will be interesting to see how good this software is...
