I dnt have one, I had used it for almost 5 months when I was living with a frnd named Hammad. its gud. it retina display is really cool I luv it!
N processing is damn fast, even with 52 apps present on it. I'm not kidding. its true about the 52 apps.
This is slim, light weight, screen is clear very gud view it gives of snaps. its slimness is very thin as comapred to Macbook Pro n Asus A555L. which is gud. N it is not having the problem of creaking noise when using for often multiple times.
But the major defect I felt was lack of cd drive. Ya I knw its a modern world but still we need cd drive for many purposes. N its really anecessary part of a laptop. it must ne there in it. N its not! that's what I hate really really badly??!
