[Dilemma] between 2012 MacBook Air 13" OR 2012 MacBook Pro 13" Retina

Hello good people,

I am hoping to purchase my next macintosh. But I am having a huge dilemma between the air and the 13" retina. Would anyone owning/used one of these and can give me some pros and cons please?

I am currently a computer science student @Ottawa, Canada, and my day to day routine are: web browsing, lots of coding, and very minimal gaming..

One side of me think the 13" retina has more ports, beautiful screen, and seem to be faster hardware in general.

But the air has the industry recognized slim body design, and the price seem to be more reasonable.

appreciate all your help...:-)
