90% of people buy MBs/iPhones/iPads and do nothing but surf the internet and social media with it. Not even that with the watch. Stop acting like people buy Apple stuff for rational reasons, it’s a fashion statement for many.
Some people use them as fashion accessories, sure. People also pay Samsung $1,800 for a foldable phone and I think that's a bigger fashion fad than my $800 iPhone. The "Apple is just a fashion brand" thing is played out and untrue. They learned from the iPhone 6 quality debacle and have increased build quality. Apple has probably the best device ecosystem out there right now from both an integration and quality perspective. There are things they can improve, and sometimes their designers are a bit egotistical, but generally they make good kit.
Circlejerking aside, people do buy Apple stuff for practical reasons. Social media and internet are practical uses of tablets and smartphones, as are email, SMS and other forms of communication. People are electing to use smartphones for general computing tasks instead of having laptops and desktop PC's, doing their banking, shopping and other lifestyle-related tasks fully on mobile devices. Apple has devices that are competitively priced for this compared to their competitors and work just as well, or better.
Many people have replaced a traditional laptop with an iPad or other tablet for general computing needs. At $749 an M1 iPad Air with 256 GB of storage is generally as powerful as (or more powerful than) a $749 Windows laptop, and you get word processing, spreadsheet software, video editing software and more included. But if you want a laptop MacBooks are typically built better than other consumer grade laptops in their price range and tend to last longer. At $999 (but often discounted on Amazon) the M1 MacBook Air is a great laptop at a competitive price. Plus they come with the same software for general productivity, video editing and more as the iPad, all software that you would have to pay extra for on a Windows laptop.
Smart watches can also be practical. I personally wear an Apple watch to help monitor my heart rate and it is also a great productivity tool. It helps me manage my schedule and keeps me updated on things that are important without having to keep my face glued to a phone screen all day. I can use it to display my boarding pass from my wallet when flying so that I don't have to take my phone out of my pocket and fumble with it. The SE model has a great set of features and is very competitively priced compared to other smart watches.
There's little that's practical about VR headsets at this point, regardless of who makes them. I'm sure some people are going to buy an Apple VR headset just because it's part of the Apple ecosystem. I'm sure it will be well integrated with their other devices. But Apple is going to have to make it more than a trinket with their logo on it to move the needle on mass market adoption.
