The Roku 4 has big shoes to fill. It's taken over two years for this latest model to come out ? the Roku 3, which we dubbed the gold standard in streaming, came out in 2013 ? but the end product has justified the wait. The new, $129 (about £85, AU$180) Roku 4 is faster, more well-rounded and more open than any product the company has released before, borrowing from its predecessor and adding more to its legacy in equal measure. It's faster because it's sporting a new quad-core processor for 4K, 60 frames-per-second video streaming. It's more well-rounded, thanks to the universal search function that scans streaming services, like Netflix, Amazon Prime Instant Video, Vudu, YouTube, M-Go and the Google Play Store for movies and shows and displays the cheapest option first. (Of course, it will scan the UK/AU equivalents when it eventually reaches those territories.)Roku is still the most egalitarian streaming set-top box of the day. It doesn't care if you pick Netflix over Amazon, or Vudu over Hulu. It doesn't want to sell you an Rdio subscription, and it could care less if you join YouTube Red. At the end of the day, all Roku's new device cares about is getting you to the content you want through the most affordable means possible. It's entertainment on your terms, the epitome of the cord-cutting movement.
