To be honest I use it every time I see a quilt pattern I like. I can redraw any block in EQ. It's simple to do. At the last big quilt show I attended, some vendors had the rule no one was allowed to have pen and paper or to linger and study a quilt that was hanging in a vendor booth and certainly no pictures. EQ makes it so easy to do the same pattern mostly because the designer used EQ to design it in the first place. :D Mostly I use it to make the blocks smaller or larger and to show the rotary cutting.
