Slingbox, the company behind the popular set-top box that allowed the streaming of content from a home cable connection to another device via the Internet, has announced a new device, the Slingbox M2. Replacing the M1 that arrived last year, the new M2 variant will cost buyers $199, and will likely appeal to those who want to stream live television from their home cable boxes, pumping it out over the Internet to perhaps a mobile device or Smart TV.
