You buy an expensive 4K tv today. Then what? Wait until there is something anything to see on it?
And in two to three years when there is a modicum of content your three year old tv is outdated and cheaper and better ones are hitting store.
You buy an expensive iPhone 7 soon. Then what? Wait until there is some things updated in the app store to take full advantage of whatever new it brings?
And in two to three years when there is a modicum of apps updated to take advantage, your three-year old iPhone is outdated and (not) cheaper but better ones are hitting stores.
See how that works? Try it with new Macs. Try it with new iPads. Try it with the Watch. Why is only this ONE Apple product viewed differently?
And for the 1,000th time, a new 4K

TV doesn't force anyone to buy a new TV if they are happy with whatever they have now. Better hardware can easily feed lessor software to 1080p or 720p televisions already in our homes. Yes, to see the 4K that would be available at 4K would require a new screen capable of 4K but guess what: to use new tech advances in new iPhones/Macs/iPads/Watch requires one to buy new iPhones/Macs/iPads/Watch. That's how it works. Don't want to use the latest new features in new iPhones/Macs/iPads/Watch? Stick with the device(s) you have now and you'll keep using the "status quo" as you do even though there are newer models available. This is EXACTLY the same.
Once again for the 1,000th time: those who feel happy with the "status quo" would not be affected in the least by Apple rolling out hardware capable of a little more... just like those happy with iPhones/Macs/iPads/Watch as is are not affected by Apple rolling out updates to any of those. What a 4K-capable

TV WOULD DO is let
another group of buyers- fools, dummies, "no ones", money-wasters, gullible, stupid, "can't see the difference", etc- get what THEY want (too)
by buying an Apple product instead of someone else's STB.
More simply: have it your way and EXCLUDE people from buying Apple products. Evolve and you get to have it your way and they can be INCLUDED too.
Which is better? For you, it makes no difference at all. For them, they get what they want. For all of us, more

TV owners means more market demand and thus more temptation for even more

TV-accessible content, content deals, etc. For Apple, more sales = more profits and more attention allocated to this product. For AAPL shareholders, more profits equals happier owners, and maybe a "buy" (more) order.

If you can think beyond yourself- aka "think different"- the better option for you personally... and everyone else- including Apple and AAPL- should be obvious.
