Roku
The top-of-the-line Roku 4, for $129.99, works with 4K ultra-HD TVs if you're lucky enough to have one, or regular HD sets as well. The small box (at 6.5 inches, a little bigger than Apple's) plugs into your TV and connects to the Internet, providing access to more than 2,500 channels (some of which cost extra). One app specializes in 4K video content. The Roku 2 and Roku 3 boxes offer many of the most popular features, but not 4K, at lower price points. All include USB and Ethernet connections for streaming personal media like your family slideshows. CNET calls the Roku 2 "the best value of the bunch.
