While that might make setup a bit more messy than Google's dongle, Lenovo's Cast should be a bit more versatile. With dual frequency WiFi (5GHz and 2.4Ghz), the disk will let you cast in most formats up to 20 meters (65 feet), even through walls. The DLNA and Miracast capability also means plenty of video, image and sound formats will be supported, and you can mirror any content from a smartphone. All that will cost you $50, which is a bit more than a $35 Chromecast, but the same as Roku's Streaming Stick and Amazon's FireTV stick (though the latter also includes a remote). The Cast will arrive this August at the same time as Lenovo's incoming Surface 3 competitor, the ThinkPad 10 tablet.
