That's what the upcoming MacBook Air 12" laptops are going to be made out of.
Each new major iteration (in terms of industrial design) of the MacBook series has introduced a significant industrial feature. Whether it was the unibody nature of the construction, or the 'thin yet full-size' nature of the laptop, this was then translated over to the rest of the series.
The liquidmetal material will first be used to produce the retina MacBook Air 12", before translating over to the other. We may even see the iPhone getting the material, despite being in the 'S' phase, for the iPhone 6S (allaying the issues with the strength of the phone).
As Apple has an exclusive right to use the material over, they'll have a significant advantage that other competitors (like Samsung) cannot simply copy (not dissimilar to the situation when the first aluminium laptops were produced, and then the retina displays of the iPhone, and then securing sapphire facilities for the iPhone 6).
Can't wait.
