Best thing I have ever used in my life.Simple, lucid and a total fun to use it. It is a costly gadget but once you have it one can do anything he or she wants.A sleeky design with siri os makes you feel special. Battery backup of macbook air is awesome .It works for 12 hrs non stop when one fully charegd.The safari browser enhances the browsing experience.An excellent security features, the data is totallly secured in Mac once you saved it.I will recommend you all to download flux software in Mac for better viewing experience in night time as this software automatically adjusts the light according to day and night.So without any further think on it go and get your macbook.
