My partner and I had a similar "oops"

We started down the path of developing a Google Latitude-like system before Latitude had been publicly announced. Our prototype apps quite literally had the same workflows and functionality that you'll find today in Latitude. So, when Google announced their intention to release Latitude for the iPhone, we killed the project.

Fast forward to today, Apple blocked Latitude from happening on the iPhone and if we'd put in another month or two of work we may have been successful. What's the moral of the story? I guess I might not stop executing in the future just because it looks like the market isn't viable or someone big is poised to eat my lunch. Then again, that could be a recipe to end up penniless or hungry.
