Games requiring a more powerful device. It potentially other stuff too.
How often is a TV replaced? I am not sure about other people, but I would expect a minimum of 5 years, if not more. Compare the differences between the ATV3 and the ATV4, which was only a few years apart.
If Apple released a Television only a few years ago based off of the hardware that's was on the ATV3 at the time, that TV would have been obsolete in a few short years later.
Yes, things like Netfix and Hulu would be fine for a while, but stuff like games that could benefit from new hardware would suffer.
My TV’s get replaced when they completely die. On average 20+ years.
To that point, I’ve purchased 2 new televisions in the last 5 years. But that was to add to additional guest room areas. Not to replace any prior televisions.
I pushed my old tube televisions to their death. Extending their lives as far as possible with digital converter boxes when the broadcast signal changed. And then with the occasional smack to the side to keep them working (who knows what that does, but something shifts and causes them to work again). Sometimes a smack on the left, sometimes on the right. Sometimes the left then the right. And if that didn’t fix it, usually a swift kick to its face did.
I really miss old technology. Can’t fix any of the new stuff by beating it anymore.
Anyway, if I purchased a new TV today with integrated Apple TV, I can guarantee you that I will not replace it until it ceases to function. And I can also guarantee you that in 20 years, the current Apple TV function of said TV will be useless (most likely within 5 to 8 years). Meaning that feature will be unused and replaced by an external box.
So... why pay Apple’s premium price for a TV that will essentially lack that feature before I’m done with it? I’m not paying extra for features that disappear on my television.
That’d be like the TV comes with a cable connection that in 5 years will self dissolve. Then I got this screen that is missing the reason I paid extra for it. Doesn’t make sense. A television should simply receive airwaves and display them, with connections to attach whatever I might want. Anything more is a waste of money to invest in.
Now, if Apple would guarantee that current Apple TV implementations will work forever with everything to the exact level that they do now, that might be different. But... connect the very first AppleTV to the current iTunes software and to the current iTunes Store for streaming. See how well that works. Then we have an idea of how useful an overpriced television would be with AppleTV integration.
From the flip side... unless I move, I now have a television in every guest area of my home. With the exception of a guest house that I’m renovating. So... if I could no longer get an external box to add to my televisions, and could only get AppleTV by buying a new Television... then that means Apple is automatically going to be waiting 20+ years before I’d be a potential customer. Because I certainly am never buying a new television just for features. Won’t happen.
The same applies to any other such company out there. I’m not buying a new screen to get access. I might buy a new cheap external box to plug into an existing screen though.
This is the same reason I’m not an iMac buyer. I don’t dispose of useful functioning devices to upgrade something else. I will keep using a keyboard, mouse, and screen. So the iMac to me is a waste. Why should I buy a screen that is useless if the computer were to die? But I also find the current mini and pro to be literal jokes at their current price and specs. So Apple hasn’t gotten money from me in a while. So why should they hinder themselves in the same way with televisions??? Aside from the fact that it’s Apple, and they’d cut off both of their legs if it meant a short sighted goal of cash could flow in, even if it lacked long term sustainability.
