The main differences between Roku players include the price, the speed with which users can navigate the interface, and the presence of additional features, including USB and SD card slots. The differences also include the type of remote that works with the device and voice search capabilities.
Of the four available models as of 2015, including Roku 1, Roku 2, Roku 3 and the Roku Streaming Stick, Roku 1 is the only model that doesn’t feature a built-in dual-band wireless functionality. It is also the only model that doesn’t include an updated Netflix app and isn’t capable of streaming content from YouTube and Netflix apps directly to a TV. Unlike the Roku Streaming stick, with which it shares the same price, Roku 1 supports universal remotes that use infrared technology and includes an older version of the Netflix user interface that works faster. It also features analog video jacks, ensuring compatibility with most TVs.
All four models support the HDMI interface, feature over 2,000 streaming channels, and provide users with access to more than 250,000 movies and episodes of various TV shows. The advantage of Roku 2 and Roku 3 players over the remaining two is that they include an improved processor and feature Ethernet, USB and SD card slots. Roku 4, as the most expensive model, also features a voice search functionality and includes a remote with a built-in headphone jack.
