The real problem with em (etc.) font-rendering in not so much "pixel
rounding" as is the use of dissimilar algorithms by different browsers to
determine a value. I would further hazard to say that browser variations
are more often a problem to markup authoring than simple standards non-
compliance.

But sometimes it's necessary to use ems, etc., such as in sizing a
container where percentages refer to a completely different dimension.
