Why would I get a mac, when I could get a PC for much cheaper and it will be faster and I'll have more control over the hardware.
Why would I get a iPhone, I can get a cheaper Android and have more control over how I use it.
Why would I buy Windows when I can get Linux which is more powerful, customizable, and free.
Not everything can be reduced down to specs and numbers. Everyone has different use-cases.
