I was planning on getting the new updated 13'' 2.53 Ghz, 4gbRAM,320Gb Harddrive Macbook Pro, and after reading different posts on different threads started to wonder if it run it ok. I thought that the dedicated graphics card on the 15'' only helped mostly for 3d modeling stuff. But, I am a photographer and only use Photoshop. Screen size doesn't bother me, since i already use a 12'' tablet as my main moniter. So I am used to the small size now. So, I'm just worried if it will do the job. Thanks so much!!
