To those upset about this not coming to older TV's: Apple TV. Fixed.
i totally agree with you, and i'd extend it furthermore: no new TVs shall be smart.
to be honest, the whole smartTV stuff is a big ripoff. usually TV-sets (display) last much longer compared to the "smart" part. if you cram to much stuff into a tv-set, it will render the whole stuff obsolete faster that it should. obviously tv-set manufacturers see that the regular "features" like 4k (which is pretty much pointless in sub-65" screens), and the absolutely-useless-8k-pipe-dream will not produce them enough recurring annual revenue, so they went down the "smartTV" way. still releasing newer and newer models maybe every 6-12 months with no visible improvement but only a $2 more expensive arm based SoC to run the os on, and more recent sw. and they have no intention to support the "older" generation devices with sw upgrades, silently forcing you to upgrade to their newest model to get the most recent (gimmicky) smart-features.
i would just buy a simple set with HDMI switching and built in speakers. i don't need no aerial support, tuner, analogue-in, or any of those non-maintained crappy applications they preload onto the pretty much closed and buggy ecosystem they have. is there anybody out there who develops for webOS at all?
the stuff is slow, the remote is over-complicated and bulky, the UI is terrible and i can not endure waiting for a stupid display to "initialise" so i can switch fckin inputs.
and as the result this whole mess you have a lot more e-waste. compare to them, apple is lightyears away in terms of recycling and product lifecycle. how come that apple can still run the most recent iOS on a 5 year old phone with quite ok performance, and LG/Samsung can not support the next gen of their crapOS on one-year old TVs? i doubt they maxed out the possibilities in the CPU in the previous generation... and i also doubt that they intend to fix vulnerabilities in older code...
