Conclusion: There are a lot of media streamers on the market. Without a doubt, every one of them has perks and provides a little something that your system didn't previously have. That said, it's hard to beat the options that are being offered under the tiny chassis of the Roku 3.
Pros: Endless entertainment for under $100, Supports 1080p, 7.1 and 5.1 sound for all (where available), Hundreds of programming choices, Integrated headphone jack on the remote
Cons: Plastic or a Paypal account is required for setup, No official YouTube channel (but there are workarounds), No 3D support, No PC-based streaming, Device is always on
Conclusion: The Roku 3 is a decent TV set-top box that will offer plenty to most people looking to "cut the cable" as Americans would say. While there are some annoyances with the interface layout and a lot of dross in the app store - do you really want to pay £1.49 for a puppy screensaver?
Pros: Small, easy to setup, lots of services supported, microSD and USB support, headphone jack on remote for quiet listening, 1080p support
Cons: Lots of dross apps in app store, can't buy movies or shows, no 4oD or ITV player, nine tile limit in interface & not best use of interface space
