Touchdown! Greaser!
Roku just plugs into an available HDMI port, and it does require power through a USB cable. My old-ish TV has a USB port right next to the HDMI ports, so I plugged my Roku stick into that for power. But what I didn't know is that USB port wasn't really designed to provide enough current to power a Roku stick so it would sometimes reboot or go offline. I had to connect it to a different power supply. The Roku setup connects it to your WiFi network and you're in bidness. My TV defaults to the last HDMI input, so when I turn on the TV it starts right up on the Roku menu. Basically, the Roku is always on. The advantage of Roku is -- it works. Smart TVs, like one that I have, do have all the apps built in, but the TV hardware and internal apps will sometimes lose support for certain apps. I have that problem with one of my TVs and my BluRay player. Both of them no longer support certain streaming services. So even though I have a smart TV, that one also has a Roku.Roku may be great, I just haven't any experience with it. I generally try to avoid appliances the require extra connections that I seem to always be troubleshooting. Roku I assume will require another power connection plus likely the HDMI cable, and then configuring TV to select the correct input for it. Simple enough, but not as simple as the Plug and play Smart TV, which seems to be complex enough setting up Wifi and subscriptions.
Not sure what level of subscription my son is paying for Hulu haven't noticed that Ads, but haven't only found it to have limited content i liked, or haven't already watched enough times I don't need/want to watch it again.
I do pay for the Ad free netflix. sure there are other good services but try to limit how many subscriptions I am paying for to a minimum and something I actually use.
