my co-workers wife uses microsft office on a regular basis, i introduced her to starOffice and after she played with it for a while, she convinced her boss to buy it for her. i have heard from a few people that starOffice is a better product. im not an office suite power user, so i cant give a good assesment of the two products, but i can say i prefer starOffice over microsoft office. i made a time card for work in microsoft office, and the file was 46kb, i made the same file in starOffice, with the same functionality, and the file was 9kb.
anyways, im glad that sun is pushing their office suite harder, and taking swings at microsoft. hopefully more people decide to switch.
