yeah, I used to switch inputs to my AppleTV when I wanted to use something like that.. nowadays, my TV has fairly decent apps (except no Roku+ or whatever it's called so I can watch that Weird Al mockumentary some eon.. will prob watch via AppleTV at some point).. oh, and no AMC+ app on my TV either (to use the last couple of days of the dirt cheap year subscription I got to catch up on Halt and Catch Fire.. though I have the last couple of eps on my TiVo still if absolutely necessary.)
But having new episodes show up and be able to delete them after watching them from streaming is a good feature, and I'd use it more IF the apps actually launched reasonably quickly.
Heck, I'd probably put up with the slowness IF the actual experience once you were in them was MUCH closer to actual TiVo UI (plus a bit of added delay due to streaming)... e.g. FF/rewind/skip forward/skip back, etc., acting like a Tivo..
