I have always used AIM, and they have some cool features that I like. However, for professional photographers, this new Yahoo IM could be utilized for keeping in touch with clients, transferring large files, posting shared folders and more. It includes a voice mail feature and something that I know I will be using - a plugin that allows discussing an image, creating a flow chart and annotating it in real time with clients.
