Roku saw the potential in digital media players well before companies like Amazon and Apple did, and it’s already used that head start to dominate the market, but with its competitors releasing some pretty enticing devices like the new Apple TV and the new Fire TV, Roku is going to have to step up its game if it wants to stay on top. That’s where the new Roku 4 comes in. The new digital media player was officially announced last night, and it has some new features and hardware that are sure to give the likes of Amazon and Apple a run for their money.
