What's different about this kind of console debugger is that you have 
the power of the entire language at your disposal via the interpreter
at a given breakpoint.  This is a bit more powerful than typical 
debugging capabilities.
It goes beyond just inspecting the values of variables, one can actually 
execute commands and process data
at any given point of the program with the full context of the program 
at the breakpoint.  That's pretty powerful and is often used in 
scripting languages
and is probably one of the reasons why Matlab is so incredibly 
productive for science and engineering problems.
Yes it's nice to have a graphical link to the source, but given a choice 
I'd take the GHCi breakpoint capability over the visual link to source code.
