But I already have to babysit a NAS and a media server
Is the NAS TV related? Why do you need these? My media is all on my PC, and I don't consider maintaining that as part of my TV burden. I have to maintain it anyway.
And what maintenance do you need for the PS and XBox? You just turn it on when you use it, and let it auto-update.
Can the Roku remote change the input source on the TV?
Fair point.
Normally, I change the source only once during a whole session, so I do that right in the beginning if I need to.
