My everyday Apple, Macbook, Iphone, iPad, iPod and Android

Hello
I am the new user of Macbook Pro Retina.
I just bought the Macbook Pro Retina a few day ago and Really feel good on the design.
A whole my life used Window OS and this is the first Mac for me
so I still don't know much about the things inside
How to work and use the Apps , Keys ,Installing,Uninstalling, finding apps something like that
coz I m so new on Mac.
Im used to on The iPhone, iPod, iPad and Android.
but I thing I will love Mac as I expected.
 Here is my picture od my new Macbook Pro Retina 13"
