Apple's New MacBook is finally available to the public and it certainly has the MacBook Air feel to it. According to Apple CEO Tim Cook, the new MacBook is "the most extreme and efficient notebook we have ever created." The new MacBook is slightly lighter and thinner than the MacBook Air, which on the other hand, is a bit more powerful. So should MacBook buyers go for the new MacBook or the MacBook Air?
