I would say auto removes a lot of redundancy in code, and redundancy is
usually bad.
I guess the best way to see its advantages is to rewrite some of your
code with auto everywhere you can. You should eventually see that the
code is far more legible and cleaner than before.
auto really is a small advantage that works wonders in this regard.
As Jonathan M. Davis stated very well, I expect it to have a huge impact
on C++11 code legibility, especially if it is used in libraries as well
as in application code.

Another reason, is it makes changing types easier, both for humans and
for automated tools, because you only have to change types where necessary.
