I think it's great. It was cheap. I'm a fan of Roku (been with them since 2008 or so).
I'm disappointed to see these tiffs with content companies. Remember the time when every video you wanted to play on your computer required a different software player? Are these companies planning on re-doing all that with hardware?
"Oh, I have a Roku for most things, then plug in Apple TV for Apple+, I use the Fire stick for Prime Video, and the Chromecast allows me to watch YouTube TV! I just needed a TV with 17 HDMI ports!"
