I'm looking for a new laptop,particularly one of the new macbooks. I will be going to college next year, majoring in Computer and Information engineering. I'm not a hardcore gamer. Right now I really can't decide between: MBA 13": 1.8 i7 / 4GB ram/ 256GB flash drive MBP 13": 2.9 i7/ 8GB ram/ 750GB HDD both have the same price of 1500$ P.S: Is it okay to not have quad core at this point? what about dedicated graphic card?
