Adam mentioned something about this. PDFcasting has been done—-after all, iTunes manages PDFs, though they can’t open in iTunes itself—-but it’s a novelty. I’m certainly not going to say it will never happpen, but here’s the prediction I will make:
PDFcasting will not take off until someone comes out with a “PDF iPod”. And then it will rock.
Because the “PDF iPod” will not be like an iPod at all. It will have a large screen, and display essentially magazine content. And with luck, it will be made of electronic paper.
It’ll come. Just wait. It’ll come.
