This would be my 5th P&P item, and just like the previous 4 things, I love love love everything about my Commuter. It's study, the "leather" feels smooth and soft, it's an organizer's dream with all the pockets and space. I love that it now has an inside pocket for your water bottle too. There's really nothing I would change about it.
Only thing I will say, just be careful with carrying heavy loads for long periods of time as it can be taxing on your shoulders and back but I think that would be the case with any backpack.
