My feelings exactly, Dave. Here’s an example:
Back around the ‘turn of the century’ I sold digital still cameras for a major, nationally known camera store. A small company named Imagek spent maybe 2 or 3 years dragging a non-working prototype around to various trade shows. The device would have been quite clever. It would have fit inside most any 35mm SLR (& many point & shoots) without any modifications, & allowed you to shoot 1.2 megapixel digital pictures with it. You could pop it in & out at will. But, alas, it was only a ‘non-working prototype’. By the time they finally had a ‘working’ prototype (which to my knowledge never produced any pictures that anyone outside the company saw), consumer grade 2 megapixel point & shoot digitals were selling in the $200-500 range, which was a lot less than Imagek wanted to sell their mock up for. Can you say ‘out of business’? Sure you can!
