Google has announced the availability of the new YouTube Client for the BlackBerry Storm. That's nice, though the Storm's touchscreen could handle the site's web interface just fine.
Anyway, YouTube client’s features include:
Browse millions of videos, including most viewed, top rated, and the day’s featured videos;
Access your YouTube account on your phone and access your Favorites, Playlists, and your own uploaded videos;
Upload videos directly from your phone and see them appear within moments on both the mobile site and YouTube.com;
Favorite, share, rate, and comment on videos directly from the mobile website to other YouTube users;
Find the specific video you’re looking for by easily searching for it;
Discover “Related” videos for each video you watch on your phone
