Oh dear god, I think there are so many things wrong on your comment. So you think I am an Apple fan, which to some extend I am but let me tell you how big fan of Apple I am. I use iPad Pro, Apple Watch original with 2 sport wrist bands and Apple TV. Then Galaxy S8 for a smartphone. For a PC using HP Pavilion. I love iPhones but I keep switching back and forth. I didn’t like the fact Apple keep same iPhone design for years and found these thick bezels unexceptionable for 2017 and bought Galaxy S8. So you see, even though I love Apple products, I always try other stuff too. The trend you are talking about is BS. Apple arguably makes best quality hardware who for most do work straight out of the box , extremely easy to use for even 2 year old kids and I think therefore they are extremely popular. I have my Apple Watch not as fashion accessory but as a health tracking device that I use daily on my workouts. First generation and still loving it. I have tried many Apple products and honestly can’t pick one that have disappointed me. And then you have to wonder why Apple products are so popular. But obviously you have your own theory which I do find it laughable but let’s agree to disagree.
Saying that you haven't been disappointed by an Apple product makes you an Apple fan. Now, to be clear, there is nothing wrong with that.
I'd been using Apple products exclusively from 2001 until 2013, and I tell you I have been disappointed by pretty much every new Apple product since 2012 (Pencil aside): iOS 7's design, MBPs with soldered RAM, the Mac Pro, iOS devices with little RAM, the removal of features with every subsequent product iteration, that AWFUL keyboard on the new portable Macs, the absolutely ridiculous TouchBar...the list goes on and on.
But just because you personally didn't buy an Apple product for it's trendiness doesn't mean Apple isn't trendy. There's a reason why someone like Angela Ahrendts is at Apple. The company is positioning itself as a fashion/luxury brand, which relies on trends and setting them in particular.
Apple is very much a trend-setter in the industry; it always has been. To say otherwise is simply foolish. In the past, they did this through the brilliance of Steve Jobs's vision and taste. But he's not there anymore and it's starting to show.
Apple's position in the industry as a trend-setter, coupled with their sometimes boneheaded decisions, can lead to the entire industry following their path and leaving less sensible options out ther for us that want them. Hopefully, some companies will decide to NOT follow Apple in everything, like Sammy did with their latest Galaxy devices (actually a reversal, since when the Note5 came out they were in the same "remove, remove" attitude Apple has). But one good influence I see is that everyone is making their devices easy to use, so Apple doesn't have that to themselves like they used to.
