Minitube is a native YouTube client.
Edit By BS Editor: Minitube is a native YouTube client. With it you can watch YouTube videos in a new way: you type a keyword, Minitube gives you an endless video stream. Minitube does not require the Flash Player.

Minitube is not about cloning the original Youtube web interface, it strives to Create a new TV-like experience.

Minitube is in its early stages. It lacks many features I planned for it. That said, it works. Try it, report your experience in the comments and spread the word. you can free download Minitube 0.5 now.
