Macs are made from generic hardware too.

THey have a mac ROM and mac-designed architecture, if that's what you mean. For me, it's the architecture that's the advantage. Yes, it is designed to work in harmony with, and complement, the software. However the parts themselves are generic (e.g. RAM, HDDs, Optical drives, PSUs, graphics cards, LAN ports, even processors these days aren't specific motorola jobs). Sure, some coponentry is commissioned especially for apple computers (e.g. logic boards), but they're just a box of generic parts. Apples use FOXCONN, so do PCs. etc etc.
