I still love my Roku 3 very much – I still use it every day – but to be honest, things have gotten a bit stale between us. The attractive new Amazon Fire TV is a firecracker, even if it does revolve almost entirely around Amazon’s own content universe, so I tend to “see” it more often than the Roku now. For that, I feel a little guilty – I don’t like cheating on my Roku. But with the introduction of the Roku 4 and Roku OS 7, the affair is most definitely over.
The Roku 4 is an outstanding 4K Ultra HD media streamer, and as far as I’m concerned, it’s the best all-around streaming media player on the market. But what’s crazy is you don’t even have to buy a Roku 4 to get at half of what makes it so great. That’s because much of the Roku magic is baked into the software, and that software is available to anyone owning a Roku product made or purchased since 2011.
That being the case, while I won’t hesitate to recommend the Roku 4 to anyone who is interested (because future-proofing), the real meat of this review is about OS 7, and the fact that current Roku owners with no immediate plans to upgrade to a 4K TV are winning, too.
