Interesting, I didn't realize there was an upgrade available.
I'd want to see point-by-point comparisons before I decide to change mine. I do use EQ7 fairly often, but it's frustrating for me to design on it - I still do most of my creative design work on graph paper and only move to EQ when I'm at or very near the final design. If the new version has better design tools, I might be interested. I really mostly use EQ as a place to archive my designs, get fabric estimates, and to print them out for doodling quilting ideas.
I wonder if they offer a trial download of the new version.
