Again, a simple answer. It may be just as I am about to turn off the tv or projector, I decide to have a quick look around to make sure nothing weird has happened. The firesticks (And the Shield) are mainly used for Netflix, Prime, Youtube, Emby, and as an Enigma2 client with Kodi for satellite tv from three dishes.If it's not in response to an alert or some notification, When/Why do you open the browser on the stick?
None of my tv's are "smart", so yes, the stick gives me all of the above functions on good solid "dumb" Panasonic Viera televisions.
Hopefully the above explains it a bit better. I don't have any other way of viewing BI5 on these tv's, and the firesticks are doing an excellent job with all of the above programs running on them. Click on Silk, and view the camerasI can't see how viewing UI3 on the stick is an advantage.
