An experiment in developing small mobile phone applications comparing on-phone to off-phone development

TouchDevelop represents a radically new mobile application development model, as TouchDevelop enables mobile application development on a mobile device. I.e., with TouchDevelop, the task of programming say a Windows Phone is shifted from the desktop computer to the mobile phone itself. We describe a first experiment on independent, non-expert subjects to compare programmer productivity using TouchDevelop vs. using a more traditional approach to mobile application development.
