I own a macbook early 2009 ( white one) specifications cpu: p7350 C2D 2.0 gb Ram: 2gb HDD: 120G Graphic card: Nvidia 9400 A friend is proposing to trade with his Macbook Pro mid 2007 Specifications cpu: T7500, C2D 2.2 gb Ram: 2gb HDD: 120gb Graphic card: Nvidia Geforce 8600, 128mb The problem is that I have never own a Macbook Pro before and I know that in this forum many people know apple computers better than me. My question is: " Is it worth to trade? Will it be a downgrade? what will i gain?" I must add that I use my computer mostly for internet, word, excel, matlab, CAD with Coreldraw and Illustrator. Thank for your reply.
