Best labtop I have ever used. I always had Dell or a labtop with windows. So I was on the fence about switching to a MAC. My outcome was mind blowing the way it works with my I-Phone and other Apple devices is unreal. It's endless what the Retina model can do. Everyday I can't wait to learn and see what this labtop can do. And so far it has met my expectations and not once did it not do what I needed done. At first it was hard to get use to. But once you catch on you will be surprised how user friendly and easy it is to navigate this amazing Apple creation!! Run in to a jam there tech support is impeccable. Also the Apple website will walk you through any problems or guide you to customize your Retina labtop so you get 100% pure satisfaction to fulfill your Apple experience!!! Hands down best money I have ever spent on a electronic device!!! Soon I will be upgrading because every new MacBook just gets 1000 times better and better. Can't wait to see what's in store for me when I upgrade!!! So as you can see I am very HAPPY I made the switch to the Apple MacBook Family. So don't think twice go for it. You won't be disappointed that's a fact!!!!!
