The big point is that DV mode allows simultaneous voice and data in 
the one radio.  Sure, it could be a bit "smarter", like have error 
correction, and dynamically fill the voice part of the data stream 
with more data when there's no voice, but it is a step up from having 
to run two radios in some applications.

Well, that combination of power and speed isn't available in the 
amateur world here (High speed packet in Slovenia is one exception 
where amateurs have high speed data).
