The one thing that seems apparent from what Digital Creations has been saying is that you get an NTSC TV quality pictue, in terms of color, and slightly less in terms of resolution (300 instead of 330 lines or some such). These images can also be animated in pretty-much real time because all it is is just a high-res-interlace screen. Pageflipping works just fine. -- Ethan Woody Allen on Los Angeles: "I mean, who would want to live in a place where the only cultural advantage is that you can turn right on a red light?"
