Big Fan!
OK...been playing with Aperture 2 for a couple of days now (sorry for the delay, ended up actually having to work yesterday). I'm sold. The work flow is intuitive, the processing tools are very easy to use and are just as powerful, if not more so, then what I was used to in Photoshop. I really like that you can make multiple images using the same original, so I can play with different crops, highlights, etc...and compare all of them at the same time to decide which came out better. Or use different crops for different purposes...The only thing I haven't figure out yet is masking, but I'll get it soon enough.
I haven't worked with the new RAW handling bits yet, don't have any RAW images on my laptop, they're on an external drive at home(I'm in a coffee shop) and I don't have Leopard yet so I can't take full advantage of those features.
Even without RAW editing, I'm probably going to buy a license for this when the 30 day trial expires, I've been waiting for a good, less expensive, photo editing tool came out. The fact that it is a work flow and archiving tool as well is just frosting...
