Apple, Microsoft, Alphabet (Google’s parent), Amazon and Facebook dominate the tech landscape. Their dominance is so broad they account for more than 20% of the S&P 500.
There are many things to admire about Apple’s hardware and software. Apple make great looking (albeit expensive) hardware. Over the years key successes include the iPhone, iPad, iPod, and the MacBook Air. The company designs its own hardware and software. This gives them the power to make an operating system and suite of apps that are tailor-made and optimized for their hardware. Apple also operates the Apple Music and Apple TV media distribution platforms.

There’s a whole raft of proprietary applications that are developed by Apple for their operating software. This software is not available for Linux and there’s no prospect of that position changing.
