I just bought a couple of Quilting Design CDs from EQ Quilt Company, so the CD is not completely dead yet! I love that I can plug it into my laptop, have it automatically load into EQ7, which is automatically also loaded into EQStitch. Then I can put a design into the EQStitch drawing board and either load it directly to my Pfaff, or I can 'play' with it before I load it.
That said, I have loaded CDs into the stick for my Pfaff Creative Vision, so I don't have to carry a bunch of CDs back & forth btw CT and AZ. Pretty handy piece of tech!
