Have actual consumers purchased a million galaxy tabs or is some portion of that million unit figure inventory that carriers have purchased but not necessarily sold to end users?
All good points here. In the short term we're focusing on servicing customers with simpler data-driven app needs, e.g. member directories, job listings, knowledge bases, recipe books, etc. Applications in this class don't require any custom programming to fulfill their requirements and most of the customer discovery we've done so far indicates these are the types of apps that most people are looking to build. It's the old 80/20.
Data exporting is going to be available at any time; you'll be able to export data from the application in a variety of formats (spreadsheet, csv, xml, etc) and even re-import it with new/updated data to update your apps. We've also kicked around the idea of exporting an application's entire schema in some sort of format that other "application builders" could presumably read. Openness and portability are important to us.
The front end of AppNowGo that you'd use to build your applications is built entirely on top of our APIs and we're dedicated to making them very powerful. It's possible a lot of the custom programming needs power users might have could be solved with some creative use of the APIs; if anyone would like to chat more about what they'd like to see along those lines I'd be happy to start a dialog.
