I guess I'm one of the few using the Nikon View/Capture and then Photoshop workflow:
1. Suck the images out of the CF cards onto the laptop with View
2. Rotate as needed in View
3. After the shoot and after all the images have been downloaded onto the laptop, do any batch changes as needed (white balance, curves, etc.) using Capture
4. After all batch changes done, burn 'em to CD
5. Transfer the images onto the desktop for selection into the 'keepers', individual processing, etc. in Photoshop
6. Use PS to save the .PSD, big .JPG and web-sized .JPG image of the 'finished' images.
I tried the demo version of C1 when I was first getting started with my D100 but didn't find it to do much more for me than the View/Capture/PS combo. Still running 7.0 on all my machines (still running ME on my desktops), so I haven't had a chance to try the PS-CS product, yet. From what other folks are saying it might manage to change my ideas about what way to go.
