At the moment I am using a mini-pc with wireless keyboard for streaming. This works well but is a little finicky for non-technical users as you have to navigate to the site you want with the browser, click on the link, expand to full screen, etc. It also has the disadvantage of having to squint at the TV while trying to navigate from a distance.
I have tried controlling the pc with a tablet, which would work well except the smaller display area requires constant scrolling, which is a real pain. I also experimented with Plex on a different computer but that was a nightmare to use and made a complete hash of my media files.
I am relatively new to streaming as we were only able to get broadband in the past year and I have no experience with Roku, Apple TV, etc. My question: what would be the best device/technique for browsing different sites from the couch with an absolute minimum of hassle? I have a fair bit of technical understanding but this is a completely new area to me.
