rMBP 13" or MBA 13"?

Hey guys,

I hope you can help me out. Just yesterday I spilled a glass of water on my 2012 MBA and now the whole thing is ruined. Worst time ever since I'm about to start writing my bachelor thesis and now I have no laptop. You can say I am in a little hurry and I now have the choice between the rMBP and the MBA. I have no idea what to choose so I hope you guys can help me out. I've read tons of reviews and both have their pluses and their cons. I'm not yet sure which suits my needs best so I am asking you: What's your experience with either of those and would you recommend it? Any pros and cons I don't have any idea of yet?
