I have EQ5 and I've never been tempted to upgrade it. I really do like it and I'm glad I have it, but truthfully, I'm far more likely to grab my graph paper, a ruler and colored pencils when the mood strikes to create a pattern or graph one from a picture of a quilt I like. But when I do take the time to pull up EQ5, I really enjoy it and will spend quite a while playing around with it!
