Minitube is a YouTube desktop client which allows you to surf and watch YouTube on your desktop.
When you install Minitube, all you have is a desktop client with a large search box. Type in your search term and Minitube will suggest some predictions for you to try. Results are returned instantly and you can view videos normally as you would in YouTube.
There's not much more to it than that though. There's no way to view comments and there's no way to download clips which would have been a welcome add-on to the interface. The idea is to create a more TV like experience but YouTube is different to TV and you cannot help but feel is takes away functionality from the site. I also experienced frequent freezing and hanging while watching videos.
If you don't have access to a web browser or just want to watch YouTube videos without all the extras, Minitube might be just for you.
