I have Aperture, I do like it but it seems kinda clumsy to use, mostly I work with iPhoto for organizing and then take them into photoshop. I do like the istock plug, but you still have to fix the titles of your images, currently it inserts the jpg name.
Is this a clumsy program or do I just need to get used to it?
I love it personally - use it to manage all of my images on the different sites i submit to - have folders for what's been accepted/rejected on each site. The image editing often saves me from going to PS to do edits too. It isn't perfect, but in my mind it is very useful for managing and editing my collection.
