Passo 1 MacBook Unibody Model A1278 Teardown  ¶ 

  • Apple boasts that, "The new MacBook packaging is 41 percent smaller than the previous generation" and is made from recycled material.

  • To be fair, though, it's about 12 percent thinner than its predecessor (0.95 in vs. 1.08 in) and 10 percent lighter (4.5 pounds vs. 5 pounds).
