The problem with the above set is that it does not give the impression 
of "yes", "no" and "you haven't set this up yet".

I have seen this addressed with two radio buttons (or more) with none 
selected until the user clicks the first one.  After that it works like 
a radio button group.

I think this might be a hole in HIG, but others would know better than 
I.

Another approach is to dim Done or Save until the user explicitly 
selects an option.

All this assumes that there is something wrong with simply using 
default values, which might be the case in some situations.
