However, it's not hard to imagine a technology in which some portion of the
display is animated, while most of it remains static, allowing just enough
power consumption to support the animation.

What I can imagine is not a lot of consideration by the page designers
for that kind of thing. Advertisers would buy animation on the pages
and users would simply have to pony up for more batteries.

Look at the web for a model. (It's why I have unplugged every animation
patch I can find).

You don't think advertiser supported approach charts are in the future?
I sure do.
