Ed,

I kind of thought you might disagree.  Comments below.

So because I don't like MDA I have a pathological need to do menial work
in to order to feel in control?  Wow, that's a leap.  I guess I hit a 
sore spot.

A users intuition doesn't change based upon the time savings derived 
from machine generated code.

I agree that generating getters and setters is menial work and I 
appreciate tools that can accomplish this task for me.  My point is that 
an application is much more than a bunch of business rules and machine
generated controls stuffed into a properties view table.  Yes, it
may be functional, but from a UI design standpoint it's really crappy.

If a UI was simply a bunch of boxes and labels then I would agree with 
you.

No thanks, I won't be attending any modeling sessions at EclipseCon.
