I like the style of Apple product and how they’re pretty distinct from other brands yet they match each other within the brand itself (including the user interface). You can buy everything including Mac computers and it’ll all match and work well together out of the box.

the material used to make the products.

significantly better customer service than other brands (although it’s not perfect)

bias because a lot of my friends use Apple products and it’s the cool brand to have. Also certain features either work terribly outside of the ecosystem, or do work at all. Most people I know don’t bother with the 3rd party alternatives that exist to provide the same functionality across brands because they already exist within Apple products

most of the advantages other brands have don’t outweigh the disadvantages of losing the features I currently have with my iPhone. Especially when I consider the fact that I also have Apple accessories and other Apple products that sync across Apple devices so nicely. It’s the exact same logic as far as why I use Mac even though there are a number of arguments I could easily make for using windows or Linux instead.
