It's a code-free tool to let any moron create Android apps! Now the Droid people can go crazy and flood each other with really bad apps ;P http://appinventor.googlelabs.com/about/ I'm kidding, this is very cool.
The part you quoted about quiz apps is very cool, even though it would've been near impossible to use in most of my college classes.
I have a question I hope someone can answer. I have the Sprint 4G Galaxy S phone. I need a calendar app that lets me place appointments every other week. All the ones I see only have options like daily, weekly, monthly..... I need every other week. My old Palm phone had that. Does anyone know what app has it?
