I got a Roku 3 for my birthday, and it has been the coolest gift ever. I wanted a reliable, affordable way to stream videos that I had taken with my phone to my television. The Roku makes this process very easy, and it looks great. I typically use the Plex app to do this. I actually haven't tried the Roku app yet, which apparently also enables streaming from a phone or computer, but I am eager to do so. I also LOVE LOVE LOVE the universal search function. You can search for any movie/tv show or entertainer's name, and the Roku will tell you which of the many channels are showing what you searched for. From there, it is really easy to select something to watch. If you have Netflix or Amazon Prime or Hulu Plus, there is always something to watch, usually for no additional cost. Tl;dr: Roku 3 is an easy-to-use, fast, reliable, and super fun way to stream from services you already have (Netflix, Hulu, etc) and to stream personal videos from your phone, tablet, or computer. I love it!
