Any thoughts on the 11" or 13" Macbook Air for photo editing using Lightroom 4/5 and Photoshop CS5/6? I am freelance photographer shooting sports, weddings, interiors/ exteriors, and families mostly. For weddings the volume can run high as say 3-4 thousand images. I'm currently using a Mac Pro Xeon quad core as my main work station with a 27" screen. I also have a macbook pro late 2011 ( 2.4 quad i7) as a portable machine which i hardly take with me nowadays since I edit the vast majority on the Mac Pro. Both machines run flawlessly for photo editing. My intention is to simplify my workflow. I'd like to use one machine for ALL my photo editing. Is there anyone out there using the current MBA as a primary workstation? I'd love to hear input. Maybe even the 13 rMBP maybe in my sights. Thanks for any insight.
