I think the Macintosh proves that everyone can have a bitmapped display. The fundamental tension in UNIX that I think AT&T doesn't understand is that everyone is going to have a bitmap. Bitmap display is media compatible with dot matrix or laser printers. With a mouse to point with, you've got sort of a baseline of facilities around which you can build a document environment. I think you also need a full-page display. I think we'll have to wait for Big Mac from Apple, maybe two years away, to get full-page display. I think a lot of the implications for developers is that this kind of development has to come from the low end, the Volkswagen of the document industry.
