I'm looking for a portable to do some photo editing and storing. Probably will settle on Aperture or Lightroom with the NIK plug ins. Last time I ran Aperture on a macbook 13" (like a 2006 model), the fan wound up pretty good and stayed running the whole time with Aperture. Not a pleasant experience. Has anyone noticed a lot of fan activity on the 13" when running either of these apps? Thanks.
