I need some business start up ideas please?

Question From User - Answers in Comments.

I am looking for really good ideas that can either be a product or service that I can use to start a company. The ideas must be in the technology/computer category.

For example, social networking sites (Facebook, MySpace, etc), video sharing sites (YouTube, Google Video, etc), social bookmarking sites (Digg).

But the problem is, all those ideas have already been implemented and they have become very successful. I am looking for a totally new idea.

Best answer will get more than just points....
