Hello all. Just got back from my local Apple Store where I was looking at the new models in the Macbook Air line. I was really just there to look at the size difference between the 11 and 13 inch models. But then something caught my eye. On the base models (which I was actually considering) when I opened iPhoto and went to navigate through the photos in full screen mode I couldn't get past two or three photos without the Air freezing or beach balling. I mean this would not be evident if I navigated really slowly but trying to swipe ten photos down proved to be more than the Air could handle. I thought with an SSD this type of problem would be less evident. My question is where should I put my money to be able to navigate photos lickity split? i7? 8gb Ram? I do plan on doing both Lightroom and eventually Photoshop with the Air. Thanks in advance!
