I find that some engineers with "cool debug environments" tend to spend
too much time single stepping code to "make it work" rather than writing
decent code up-front. When someone knows up-front that their debug
facilities will be non-existent it makes them think a bit harder about 
the
design and be more careful when they code. It also encourages the
creation of built-in debug and/or logging facilities in the software 
which
can be rather valuable in the field. While I value the productivity 
benefits
that come from using a JTAG to debug problems, I try to encourage my
colleagues not to use it unless they _really_ have to.

But debuggers are a bit of a religious issue ... it's vi versus emacs 
all over
again :)
