So I just bought a 13 MBPR late 13 model. My fiancé is trying to get me to get her one so I'm itching to upgrade and give her my 13 or get her an air 13. What do I do? (Use it for work school, light gaming, music) I am a speed lover! The faster the better! Let me know what you think I should do? (And yes I'm thinking the 15 for 1999)
