As it happens all the time! Any new Apple based device is first leaked in the market (knowingly or unknowingly) and later on once the perfect buzz has been setup then it is launched officially to cash upon the initial eagerness of committed Apple fans. Once again the story is about to repeat itself. The overly hyped series of MacBooks has one more sibling being added to its family. MacBook refresh has been officially launched with some regular and some exciting features. The most gripping of them all is the 10 hour battery backup that the newly launched device will provide. Truly refreshing, eh?
