I bought this bag as replacement for my similar old bag.  I found the old one more convenient with the single large opening with a divided single compartment, and more credit card, etc., space.  The old bag also had a cell phone pocket.

This bag would be improved by enlarging the small front pocket to hold a cell phone and by putting a double zipper on each of the large pockets.  It would also be nice to have an open pocket on the back of the bag to hold a folded magazine, theatre program, or whatever.
