I was reminded of their discussion this week when I came across LeFever's delightful video about RSS feeds(referenced by both Robin Goode and Stephen Downe's blogs).
I placed the cool 3.5 video on a couple blogs (View it above), but wondered how this video would show on a small screen of a portable media player (Ipod, Sansa). So I saved it to .wmv on my desktop and then moved it to may Sansa. Well my portable media play has a 1.5" by 1.5" screen. This particular session didn't do too bad, considering.
Screens w/ a bunch of print displayed poorly. I think this one would have done well on a larger display model, however.
While really good visuals complement rather than repeat text or audio content, more complex models may still be problematic for portables at this point.
I can think of something like art slides, or flashcard type screens as workable screen choices.
BTW: This video came from BlinkTV. The viewer can choose the video format for viewing. While the selection doesn't make a difference for posting to a blog, it made a difference for downloading the link from emailto a specific machine, and would make the difference for saving to Itunes/Ipod or Sansa.
