I have been using the trial version of Aperture 2. I own ver. 1. I had mixed feeling for 1 and was thinking about going to Lightroom. Version 2 runs a lot smoother. On my MBP ver 1 slowed down my mac noticeably. The new version does not slow it down. The interface is great when processing raw files.
Did anyone else find the new version better? Just thought I would share my small finding.
