Dell is looking to expand the functionality of its Venue 7 and Venue 8 with the Dell Cast, an $80 wireless dongle that plugs into a TV, turning those Android tablets into fully functional desktops.- The Dell Cast dongle is about the length of your thumb, and no larger than devices such as the Chromecast. On one end is a male HDMI plug to connect the Dell Cast to a TV or monitor, and on the other side is a full-size USB port, which lets you attach a peripheral such as a mouse or keyboard.
