Some of us don’t really like to browse XBOX Marketplace on our console. As a solution, Microsoft has launched XBOX Live Pipeline, a web browser accessible site that let gamers use the XBOX market place with their computer browser. You will be able to view lists of demos, trailers, and browse available games. Unfortunately, you will still need to use your console to purchase games on the Marketplace.
