Hi guys i'm new on apple, i bought an iPad and iPhone, now i'm interesting in buying a Mac. Here's my problem, first of all i'm from Argentina and it's a tough to get apple products, so the deal is being accurate with the product. I want to buy an iMac or Macbook. I use the computer mostly for photograph's web desing, videos (watch and make). So i don't now where to start, the 27" iMac is beautiful, but the 13,3" macbook air top configuration is also great. I'm between the devil and the deep blue sea!!!! Can anyone make my shop a profit? thanks a lot!
