Can anyone tell me for sure if there is supposed to be a difference in the depth of the interior pocket in the work bag on different years? I think the older bags (at least 06) had a more shallow inside zip pocket than, say, the 09s, but a SA is telling me the 09s are more shallow. I'm really confused b/c my 09 Granny Work has a deep interior pocket. I'm talking about the one inside the bag, not the outside zip pocket. Does anyone know? Thanks.
