the amount of time that photo mechanic 4 saves me in managing my files makes it pay for itself on a weekly basis- it's amazing- in particular the newer raw+jpeg features and email functionality are great, it allows me to instantly email or generate web galleries from low res jpegs while keeping big raw files in the background for printing or editing. and the ability to classify images makes it a snap to pick out the best images to use and come back to them later while keeping the whole take of images together in one folder. love it, love it, love it. I only wish you could customize the html outputs more- right now i still generate my web galleries via photoshop, but as soon as the next version allows totally customized web templates, i'll stop using photoshop altogether...
