"By far the easiest to use with the most features."5.0 starson by DanVM
Pros: Has a beautiful interface with tremendous resources. Works extremely well with Plex and never buffers.
Cons: There's an ongoing battle with YouTube. As of today, you can access YouTube via MyVideoBuzz and Plex. Hulu, the free version, is also not available. At one time you could access it via Plex but that capability has been taken away.
Summary: I've reviewed and tried many other streaming devices and keep coming back to the Roku. The true test is whether or not my spouse and children will use it and the Roku is definitely the box they prefer. They really do need to have native YouTube and Hulu Free apps but there are so many other compelling reasons to own this box that it is still worth every penny. Buy it at Costco or Sam's and get a free HDMI cable and month of Hulu Plus. Note that the Roku 3 ONLY has HDMI output. If you have an older set, get one of the Roku 2 options.
