There aren't many media keyboards devoted to smart TVs (they tend to be built for home theater PCs), but Logitech might have just given you another viable option. Its new K600 offers a compact keyboard-and-trackpad combo designed for modern smart TVs. You won't have to laboriously enter web addresses or search queries using just your remote. The K600 won't work with every model, but it covers popular LG, Samsung and Sony 4K sets from 2016 onward.
