I'm an iMac apple user and amateur photographer. I have Aperture uploaded on my iMac and use all of its features from folder consolidating to fine detail editing. I also enjoy 4gigs of Ram on my iMac and have had no problems with the running/processing speed of my computer. I'm also a freshman at UCB and am planning on purchasing a laptop with the just-released BTS sale. I'm going to wait until apples lineup is completely upgraded to Lion because I don't want to have to hassle with getting my programs and files off and on the computer while I reformat. My current bias is toward the Macbook Pro 15' with the high end graphics card. I decided on this because I want to have enough freedom on my computer to run a web browser and edit photos in RAW. I read on the forum that the new Macbook Air will have a significantly upgraded core processor. I also read that I can easily integrate 4 gigs of ram onto the Air. I'm wondering if with both those upgrades the Air could be a viable alternative to the Macbook Pro. If you could address the features I mentioned and elaborate/explain any misunderstandings I have, I would greatly appreciate the input. I want to do my homework and have fun doing my photo libraries at the same time!
