My non-Apple products are working even better for me, and I don't pay a fortune for them.
You have Apple TV, I have an nVidia Shield, which does everything your Apple TV does, plus streams games from my PC, has apps such as Kodi (so I can watch stuff from my NAS), Netflix, Crunchyroll etc. I also have Chromecasts in every other TV in the house, so I can stream Netflix from my phone everywhere.
My Sony MDR-XB950BT are several leagues over your, frankly, ridiculous looking Airpods and their bargain-basement sound quality.
The gorgeous 5k 27" display on my desk beats the living lights out of your 27" iMac. Plus, it's connected to a computer that's way faster, more capable, fully expandable, user serviceable and generally much more useful than your iMac.
The quality of Google applications (Photos, Maps) is leagues beyond their Apple counterparts.
The thought that you paid a lot more to get a lot less simply makes me laugh. You are taken for a ride, and you're deep in Stockholm syndrome territory.
When did this become a "how long can you pee" contest? Comparing headset like your MDR-XB950BT's to earbuds like the AirPod's like comparing apples to oranges.
My Sennheiser HD 800's and my Hegel HD12 DAC at home would obliterate your MDR-XB950BT's, but how does that relate to anything? You won't see me using my HD 800's outside the house.
I would believe that those who opt for the AirPod's do it for the seamless synchronisation and pairing between their Apple devices (Apple W1) or they do it because they wan't something small. Or perhaps even both? I'm also one who prefers headphones, I just replaced my B&O BeoPlay H7's with the new BeoPlay H8's and I bet they sound better then your XB950BT's. But is there one thing I would want from the AirPod's it's the W1 Chip, having to re-sync everytime I want to move from my iPhone to my iPad to my Mac is tedious..
And when it comes to the Apple-TV.. Sorry, but I couldn't disagree more. I grabbed the NVIDIA Shield when I got my LG OLED 65-inch B6E TV as I wanted to test out some 4K content. I returned it within the first week. I didn't like it, not at all.
I mostly use it for Plex, YouTube and a few other things. The Plex-app feels really dated compared to the one on the Apple TV (Gen.4) and the loading of cover arts is really slow compared to the Apple TV lagging the whole GUI-experience. And the whole "automatic refresh rate switching" didn't work out all that well as I got noticeable hiccups/lag during playback with that option enabled.
All in all the Plex-experience was really disappointing, especially considering NVIDIA is clearly marketing the devices heavily towards Plex. It almost feels like they have some kind of collaboration and still the app is not all that great to use...
My girlfriend kept complaining about the YouTube-app as well and how she felt the interface was horrible with her list of about 50 people she subscribes to. It was shown in an endless list with a square icon, only one for each row so she had to scroll forever to find the channels she wanted to go to.
The Chromecast software in the Shield isn't all that great either. It doesn't not support 4K/HDR like the Chromecast Ultra for some awkward reason even though the hardware should be more than capable. The game streaming isn't that relevant for us, we play on our gaming PC's and on the TV we mostly use our Nintendo Wii:U (soon to be replaced with the Nintendo Switch) or on our PlayStation 4 or Xbox One.
Another thing we also love with the Apple TV is it's great "family games" like Sketch Party TV. That was a huge hit during the holidays. Passing our iPad Pro with the Apple Pencil around family members while people was guessing while looking at the TV.
Your whole rant about iMac is just stupid. People use Mac's for a reason, and that reason is most likely related to software and not hardware. As a IT Professional myself, running my own VMWare ESXi setup, Windows Server 2016 and whatnot at home and with a dedicated Windows 10 gaming PC for myself and my girlfriend I know everything about capable hardware and I'am by no means "locked" to Apple hardware and software.
But still I prefer to use my MacBook Pro with macOS while working "in the field" and I wouldn't replace my iPhone, iPad and MacBook with anything else at this current date as I have yet to experience anything that works as efficient and seamlessly as my current setup.
It's just plain stupid of you telling other people what they should and should not enjoy in life.
