I'd rather use a dialog that's somewhat less enjoyable asthetically
than enjoy a dialog that's somewhat less usable by humans.

I don't think I'm unique in that opinion, although I can point you to
some apps whose developers obviously disagree.  Trying to get anything
accomplished with them is almost physically painful, but look!  Pretty

Perhaps they won't.  Perhaps they won't need to.  You can't say that
it would be particularly surprising to discover it does, or
unreasonable to try it out if you need that feature.  At any rate,
once they learn the first time that it works that way, they will
remember it and be able to use it, since unlike the way that the
dialog currently works, being able to consistantly use that behavior
doesn't require working against the fundamentals of the way our brain
is designed.

At a more technical level, what I mean by that is that cerebellum is
quite capable of finding the nice affordable button with the current
unit on it with rather minimal input from the cerebrium; at any rate,
no more input than it takes to find the units box normally.  It's true
that it has to look around a bit longer to find it, but it's even
capable of optimizing that to a surprising degree.

The reason for the difference is that "convert these numbers to a
different unit" is not a task that has years of convention to unlearn,
while "fill in the desired information" is.

Ony the terminally nitpicky would even notice.  The terminally
nitpicky probably have bigger fish to fry.
