Apple is the only hardware company where you can buy a product and it is good hardware wise. Sure other companies have flagship offerings but with apple you get a really good base model.
And that is where it breaks down for me. Pay 20% more for freedom? Yes, absolutely. But pay more for much worse? Yeah, not many people are going to be so idealistic.
I don't know why no one else can produce a laptop with decent battery life with an near silent fan and good display and overall great production quality. Yes, it is much easier when you are as big as apple and can rely on economics of scale but that doesn't totally explain the lack of quality when it comes to the competition.
