There are a lot of smart TVs already integrating with internet... I would imagine most would be like that in the future. It didn't make sense to me why they integrated a screen (other than to get people to use it in every room/ some sort of Amazon strategy that usually works for an unforeseen outcome).
What I haven't seen is something like the electronic-paper Kindle... a calm display. Most of the time I have my laptop and tv on quick shut-down because the ambient light feels grating (maybe it's the feeling of losing energy? not sure why it annoys me). A calendar or XKCD board would be awesome.... have the echo just populate a poster with stuff that's slightly irritating to lookup... this leads into an idea of having 'settings' for the environment/ room...hmm
And add a feature to listen to commands like "Show me X on my phone" or "Send this to my phone" and it will display whatever you just asked for on your iPhone. Or even "Send this to [contact name]".
