When companies focus on just one thing in a vertical, they're incredibly vulnerable. Samsung does lots of things fairly well, with some hiccups, well beyond just personal electronics and home appliances. It's diversification.

EDIT: Samsung does all sorts of things including ship-building, life insurance, construction and advertising.

For example, Apple MacBook Pros have become uncool, expensive, unrepairable and impractical... a giant FU to customers. That business is tettering on failure because they've been hypnotized on elixir of utopian, aspirational design rather than technical, environmental and practical usability. iPhone is the lion's share of Apple's business, and they're losing ground to Android. That's a problem and most other products have plateaued and aren't anywhere near as dominant-capable or category-defining as the smartphone. That means Apple is a basically a banana republic (pun intended) unless they create or retake a category with a non-incrementalist product.

Disclaimer: I own an A1278 13" from 2013 but refuse to buy a $3000 soldered on RAM and SSD laptop that can't be transfered without proprietary service tools and whose glued-on batteries are a PITA to change. Also the low-travel, flush keyboards are terrible. Looking at Lenovo and System76 machines instead.
