I currently use Aperture on my MacBook Pro and I find it suitable for organizing my photos and basic level tweaking. Now that CS3 is out, I'm debating whether or not to plunge into it. My only previous experience is with Photoshop Elements 3 on my iMac G5, and I honestly never used it much. That's quite probably because I never understood much how to work with various layers and other tools. Things that I thought should've been quick fixes eluded me. However, I got the impression that it handled more than I'd need to do. CS3 is universal, but I don't see a corresponding Universal update to PSE. Does anyone know if one is imminent, or a convincing reason why I should just accept the inevitable and buy the expensive package? Is my MacBook Pro 2.16 w/2GB RAM sufficient to run CS3? I'd appreciate your thoughts and experiences.
