I see two big problems with Apple producing an actual all-in-one television:
- There's a bunch of big players in the market already, who produce fantastic displays with mediocre cheap Android / Web OS interfaces. And they sell their TVs on very slim margins (in some cases recouping the loss on initial sales price by getting paid for selling your viewing data to marketers, but the general public is oblivious to that). You have to compete with them. You can make a much better user experience, but they can make the really great screens and driver electronics, which are 95% of the cost. With the current Apple TV streaming box, you get Apple's great UI piggybacked on top of all those other great screens already.
- The streaming UI experience and apps and the electronics to drive that are evolving at a much faster rate than the physical screens. A screen from ten years ago can still look really good today, while a streaming box from ten years ago is much more likely to feel limited by its older hardware. If you package the two together into one unit, then when you start feeling like your streaming experience is missing the latest innovations, instead of upgrading to a new $100-$200 streaming box, you have to spend thousands of dollars on a whole new integrated-TV, even if you were still happy with the TV's image itself. Or, you could buy a standalone Apple TV streaming box, and plug it into an HDMI input on your nifty-all-in-one Apple TV, bypassing the older built-in Apple TV streaming hardware in the nifty-all-in-one Apple TV. Not an ideal situation.
Apple could get around this latter problem by building a TV that had some sort plug-in module for the Apple TV, so it could be upgraded separately, but then you get back to the situation we have right now, just with slightly different packaging. Or, they could get around it by putting an M4 chip into their TV, but that would make the price gap between their TV and the competition even higher.
I'm using an Apple TV (4K 2nd gen) plugged into an LG C1 (along with a PS5 and Sonos speakers), and the system is
terrific, and the only times I touch the LG's remote are to watch the occasional OTA broadcast (like the Super Bowl, or Olympics - everything else is streaming). I use the Apple TV's remote for everything else (except when using a PS5 controller). The only bits of the LG's UI that I ever see is when "Dolby Vision" or "HDR10" or such pops up in the corner for a second when changing signal protocols, and the "HDMI1 - Apple TV" or "HDMI3 - PS5" notifications, again popping up for a second, when changing inputs - other than that, the LG is
just a monitor.
If Apple wanted to go one step further... build a TV tuner into the Apple TV streaming box (and put a coax connector on the back of the box), and come up with a new Apple-supplied "BroadcastTV" or "OverTheAir" app, that simply uses that tuner, putting their own broadcast TV spin on the interface (it could even use this new Apple TV's capacious storage to Tivo/time-shift a few broadcast shows, and make them appear in "Up Next" in the Apple TV app).
Maybe make this an optional deluxe box while still having the current box sans tuner - call the new one "Apple TV Max" or something. Then the user could hook up an Apple TV box to any current TV set
or any computer monitor, and have a full "TV" system, and never have to touch their TV's remote again.
