I use Hypercard in nearly every aspect of my life! I have done so many wonderful things with Hypercard and I can't imagine life without it. We all have unique tasks that we need to accomplish. Hypercard has always been an incredible tool at my side to help accomplish them. I can't imagine having to be a slave to whatever tasks the commercial software vendors think I might need to accomplish.
Hypercard is the reason I have purchased throughout my life 10 Macintosh computers. So if I represent even a small part of Mac owners, I would think that Apple for their own good would find a way to make Hypercard run on OSX.
