Ive been using the Aperture trial on my Macbook Pro for the last couple of weeks, and I think Im going to purchase it. Performance is typically ok, but I do notice some sluggishness sometimes some lag in places, which Id like to eliminate if possible. Is this typical of the App, or am I not well enough specd (I think I meet the minimum requirements)? MBP 1.83GHz Intel Core Duo 1GB RAM RadeonX1600 I shoot in Raw on a 350D, and have about 4,500 images. Ill buy more RAM if it is worth it, but if Im limited by my processor or graphics card, I may reconsider my options. Thoughts & experiences appreciated!
