I watch stuff off the internet on the computer; the TV is strictly for OTA broadcasting and whatever local stuff I want stream or play (I still own DVDs and even rent them
on occasion because there's stuff you can't get any other way).
A couple of years ago my elderly aunt wanted to watch Netflix on her TV (she'd already managed to get it working on her computer) and after a bit of research I set her up with a Roku box and she's quite happy with it (I discovered Roku had an app for the NFB
so that was a nice albeit unexpected bonus). As I said, that was a couple of years ago and the landscape has changed since then, with Chromecast and Apple TV upgrades (and Roku just announced a new lineup
also), but I think for folks who just want a simple 1080p "Netflix box" that just works
without a lot of frippery and complexity, it's probably still the thing to beat.
