I am using rhis laptop from 8 days and it is not aloke other macs so I have given discription from using it for 8 days below.
PROS
Incredibly thin. Weighs less than 2 pounds. Excellent battery life in testing. Retina Display. Great-sounding speakers. Available in three colors.
CONS
Only one USB-C port, with no adapters included. USB-C is not Thunderbolt-compatible. New keyboard and Force Touch trackpad take some getting used to. Can only be upgraded at initial purchase.
BOTTOM LINE
The 12-inch Apple MacBook is the thinnest, lightest Mac laptop yet, combining the power of OS X with extreme portability and more than 14 hours of battery life.
