One could be compatibility.
I cannot save a file as a TIFF and print from my i960 Canon printer. It only recognizes JPEG images. If you plan to print your files or take them to a photo finisher to have real prints made, you better make sure they accept your files or you may have to convert them prior to taking them in. I, for one, am always looking for ways to do no more than what's absolutely necessary to do on digital files, not more.
