Wow, that list is short...
I was using the Lightroom beta, and I loved how it seamlessly dealt with the RAW files from my Fuji S5000.
Since the beta expired, I have been debating:
- buy Lightroom?
- buy Aperture?
- use iPhoto with some other tools?
- find a good alternative to iPhoto?
Really, my first choice was Lightroom. But both it and Aperture are expensive. If I spend the money, I was thinking Aperture might be a better choice, with Apple being quite aggressive at updating their pro apps, and offering hooks into the best OS X experience. But now I realize that Aperture won't do RAW from my camera! Not good Apple, you've lost a customer.
For now I'm using Lightbox for RAW conversions and iPhoto for organizing, and Photoshop for editing. Lightbox says there will be a new version soon, so maybe I will be able to use it better.
