Planning on getting a base model MBA. How has been your experience with Lightroom 3? I should add that I am on the fence whether or not to purchase the base model or the 'ultimate'. Curious because the only true ram and processor hog may be the LR3, but even so, I don't shoot much digital, rather, I edit a lot of medium format film scans (these files don't tend to be huge). Currently a college student and plan to use it as stated above with word processing and web surfing. Any advice?
