As someone who has worked with the manufacturers of Apple's products, I can vouch for the fact that they have the best build quality you can get in a laptop. The aluminum cases are great for heat dissipation and have tons of machined features on their that look like they cost a TON, but Apple negotiated amazing deals with Foxconn that no one else can get. Honestly, I'm surprised all Mac laptops don't cost 30% more. They are unmatched in terms of longevity and build quality.
The problem is that the entry price points are quite high, and don't get you better performance. And you also have to deal with Apple software. Hackintoshes (Macs with Windows on them) I've heard are great when you buy used Apple laptops, which, for me, is the only way to go.
