I wouldn't worry about it either. Just as the jacquesm stated - Google launched when there were tons (infoseek, yahoo, excite, microsoft, etc) other search engines. When Ford introduced the model T there were other car companies. When Michael Dell sold his first custom made computer, there were many existing computer manufacturers. Ultimately if you can build something that is a better product - through price, experience or customer service, people will want yours and not your competitor. I wouldn't worry about it. Personally I would worry if your idea was so far fetched no one's even thought about it.
