I see that some people with MBAs have installed Lightroom and/or Photoshop. Can anyone give me an idea as to how well the MBA handles processing raw files? For example, is there any lag between making an adjustment to a raw photo and seeing the adjustment on the screen (i.e., when working with a raw file before converting it to a jpg file)? Also, can anyone compare the amount of time needed to convert a raw photo to a jpg on the MBA v. MBP or MB (or anything else you can compare the MBA to)? I know the MBP (faster processor and graphics card) and MB (faster processer) will be faster in converting the raw photo to jpg, but I am trying to figure out just how much faster. I like the form factor of the MBA, but I do not want to give up so much processing power that it takes me significantly longer to edit a set of raw photos. Finally, any thoughts as to whether the SSD would improve performance in editing raw photos? I don't think it would make a difference, but maybe the faster read times would help? Thanks in advance for any insight you can give.
