In the case of laptop case it is much more complicated, and their construction is not as straightforward as it might seem.
The MacBook is a brand of notebook computers manufactured by Apple Inc.
from early 2006 to late 2011, and relaunched in 2015.
It replaced the iBook series and 12-inch PowerBook series of notebooks as a part of the Apple-Intel transition from PowerPC.
For five months in 2008, it was the best-selling laptop of any brand in US retail stores.5 Collectively, the MacBook brand is the "world's top-selling line of premium laptops."6 There have been four separate designs of the MacBook.
The original model used a combination of polycarbonate and fiberglass casing which was modeled after the iBook G4.
The MacBook Pro (sometimes abbreviated MBP)1 is a line of Macintosh portable computers introduced in January 2006 by Apple Inc., now in its third generation.
Replacing the PowerBook G4, the MacBook Pro was the second model to be announced in the Apple?Intel transition, after the iMac.
Both received several updates and Core 2 Duo processors later that year. The computer's second generation, known as the "unibody" model, has a more tapered design and a casing made from a single block of aluminum.It debuted in October 2008 as the 15-inch MacBook Pro and the 13-inch aluminum unibody MacBook.
The following January brought the design to the 17-inch model, along with the built-in battery that joined the rest of the MacBook Pro line in June, during which Apple also absorbed the unibody 13" Macbook into the MacBook Pro line.Subsequent updates brought upgraded Intel Core i5 and i7 processors and introduced Intel's Thunderbolt technology.Źródło: https://en.wikipedia.org/wiki/MacBook.
