Ah, now I understand you're concerns.  No, the proposal is just for
the font-size to be based on the width of the element (rather than the
other way around).

Let's run with that though.  Imagine you have no minimum font-size,
then you're right on a 150px PDA, you won't be able to read a thing.
However you will get a very good overview of the page.  Now say the
PDA has a zoom facility (hmm.. kind of like the effect demoed on the
iPhone), then user can zoom in to the bit they are interested in and
start reading.
