Years ago I joined a startup as a junior developer to work on a patented security application with SSL certificates and stuff. They had been working on it for 5 years, 10 engineers and 2 guys with PhDs, it was serious business. The thing was a prototype but it was fun to work with them. I was porting their app on Mac OS X too because the founders were sure that it would also be a success on a Mac.

Then one day I bought a HTC Desire to try this Android thing since I already knew Java. After a few tutorials, I realized that I could clone their whole app in 100 lines of code thanks to the Android API in less than a week, but it would be better, safer, and portable. I knew we were doomed. They closed the company a few months after because no one wanted their application.
