There's always the problem of postscript having to generate complex pages. People seem to have forgotten the biggest complaint about postscript, it's lack of speed. I wonder how many here have had to wait a solid minute for a postscript printer to process a complex page. And this is a printer with it's cpu dedicated to processing postscript. It doesn't have to manage memory or run user processes at the same time.
