I'm trying to decide whether or not to add iWork to my purchase. I'm not doing a lot of fancy documents, but I do have to submit papers to instructors in online courses in Word or rtf format. Can you save a document as a Word or rich text file in Pages? I can find responses to similar questions about Pages and Word, but I don't think I've seen anyone ask if there is "save as" function in Pages. So, is there, or should I stick with Office for Mac?
