It’s no secret that Apple loves aluminum. Look at the MacBook line of notebooks and what do you see? Aluminum cases unlike notebooks of any other computer maker.
Competing PC manufacturers know that the buying public love the aluminum clad Macs, so they want to create ultra books of their own. But Apple controls aluminum supplies and the expensive equipment to make MacBook cases.
From Aaron Lee and Joseph Tai in DigiTimes:
Vendors, facing limited capacity and price restrictions for unibody aluminum chassis, have chosen new materials such as high-density fiberglass, and designs such as aluminum chassis with plastic internal parts, for their ultra book models
In other words, they’re finding it difficult to copy Apple’s unique unibody aluminum construction so they substitute with plastic or other less desirable materials.
Who’s your daddy?
