Some of the features include a 3.5 inch screen, intuitive interface, and WiFi capable with the Safari web browser and a You Tube video portal.

You can see Samba de Gafieira performed by a couple in Rio de Janero on this dance clip on You Tube.
A benefit of You Tube videos is that each video submitted has a user name so you can actually add a specific user to a list and regularly follow their video uploads.
