I have to agree on this point.  Thinking in terms of the "real world
objects"  is a concept that is much easier to understand.  It makes
visualization and flow of control of the program easier to follow.  
(Probably directly related to the way I was taught to think about
OOA/D/P.)

I know that when I have to start thinking in terms of stacks and data
structures and pointers, I get lost in all of the visualization of the
different parts.  This is why I like Squeak so much.  It makes it easier
for me to see the big picture.
