There are plenty of brands with a more limited product range and simpler market positioning, as you just pointed out. If those are a good fit for you and you like them, that's great. There's a reason macbooks and chromebooks are so popular.

I honestly don't get why someone would feel compelled to publicly complain about the very existence of products that they don't want or need or understand.
