Can we stop with this absolute fantasy about PCs that "fit in your pocket"? The medium is the message, the form is the functionality. Smartphones have been "pocketable PCs" for more than a decade already, but are dumbed down because their inputs and outputs are limited. You can't type effectively, your screen is small, your battery is limited. Would you want a command line interface on your Smart TV using only a remo…
Kinda, if the remote had a useable keyboard (I think some do).
Mostly I would like a universal search: to be able to type the name of a show, channel, or other media source and have all relevant apps or TV functions that can play it come up. Also it would be cool to enter something like "seek MM:SS" to tell the current media to go to that precise point, and universal commands across all players/apps would be pretty keen, like "captions off", "language XXXX", etc. Just need a TAB key for autocomplete.
