Because I thought I saved money by buying Lenovos on paper at least as good as the Apples. Only to have a resale value of about $10 after 3 years when time came to buy a new laptop. (If the hinges etc lasted that long.) A Macbook is more expensive, but not only did it last me +3 years, I sold it for about a third of its original price, money I used to pay part of my next Macbook. That's why.

TL/DR - only Apple devices HAVE a resale value.
