Photo Mechanic is about an inch from being THE world-class image editing software. If you could add the ability to download (on-the-fly) from the camera (tethered) while adding IPTC and renaming; A really good RAW file conversion module, and the ability to easily add graphics (such as a logo) and some other customization features to the Export as HTML dialog, I don't think I'd ever have to consider using any other application besides Photoshop.
