Plus, legal streaming video/audio has become ubiquitous in the US, and Chromecast/Fire TV/Roku are far cheaper than building a Home Theater PC (or even converting an old video game console or Linux box into one).
As an aside, I got a $60 Xiaomi Mi box and love it. It has Netflix, runs Android and is a Chromecast client (you can send videos to it). It's about the same price as a Chromecast for a ton more functionality, I highly recommend it.
I haven't tried the Roku/Fire etc though, so they may be good too.
Eh, it's Android, presumably it'll still run Kodi, and, hell, if I can't get my $800 phone to be supported for two years, I'm not going to mind my $60 TV watcher.
My 2 year-old Roku is on the same OS version as my 1 month-old one. Only difference I ever notice is that the new one is a little bit faster / more responsive.
