I developed quite a few stacks in the 90's. Always hoping to be able to move to MacroMedia Director. Never made the jump. Now I climb telephone poles for a living... I think that Hypercard should have been released on the Newton. And should have been cloned for any PDA that was/is looking for that killer app. Any device that provides Hypercard type functionality with a language with chunking (such as a much revised and updated Hypertalk) and near human commands will provide the device with the Killer consumer app. Some will develop for themselves, some for commercial or mass access. Most people will not do anything but run those apps. I think the biggest problem with the Hypercard concept for Apple nowadays is that it removes Steveie's control of people, who then may release really ugly software (visually, in his opinion). I'm pretty sure one reason for the way the iPodTouchPhone software distribution through iTunes is so Apple can control the look and feel of the Apps released. Anywho, here's hoping for a decent PDA with a Hypertalk-like Intergrated Environment.
