Was on charge overnight, the animation had stopped.  As you correctly
figured out below.

Battery condition monitoring is clearly still in the voodoo stages. 
Sometimes I think it'd be better if they didn't try, it's so random.

It didn't match my earlier uses.  (I've been very slowly integrating this
thing into my daily life; it's intended to eventually replace my Palm TX,
but so far the calendar and contacts are still on the Palm.  I've also
just got a new much-upgraded smartphone, an HTC Mogul, and I'm trying to
figure out which functions should live where.)

And relating to the ongoing integration -- possibly I'm seeing drastically
shortened battery life from having both wifi and bluetooth enabled.  Since
they're alternative connection profiles I think it should only use one at
a time, but maybe it doesn't.
