The 15 inch Mac was a beautiful creature of hardware with ultra slim and design was really good with rose and gold mix it was only few inches thick have good boost for battery life and performance but the single USB port is difficult to use many
It is very light weight to carry on journeys which is very convenient
The only problem is cant able to attach other devices while the machine is charging need extra devices to use
It gives 10 hrs of battery life while surfing the internet Iam sure about this
