Came out with an idea then realise that people are already working on that

Guys, I am wondering about this question. This is not the first time already, an exciting idea to share files across mobile devices pops in my brain. I was excited that I spend one or two hours fine tuning the idea thinking its implementation in my head before I get home.

And guess what, an app called bump is already doing exactly the same for quite some time, even they way the do it technologically, is 95% of my idea.

Have you guys come across with this kind of situation before? Please share your story.
