New here, Please help me out Having a hard time deciding on these two AIR $1647 2.0GHz Intel Dual-Core Core i7, Turbo Boost up to 3.2GHz 8GB 1600MHz DDR3L SDRAM 256GB Flash Storage or RETINA Pro $2117 2.9GHz Dual-core Intel Core i7, Turbo Boost up to 3.6GHz 8GB of 1600MHz DDR3L onboard memory 256GB Flash Storage Since i have a ASUS G74sx right on my desk. I am not gonna use this unit to play any game. Pretty much just surf on the internet, writing paper, watching video, may be some python programming.........So I donot need a beast..... BUt Does the Retina display worth the money? and Will it also worth sacrificing the protablity of the air?????
