Updated:
I'm using a smaller bag, due to the fact I don't have a personal locker at work ... we all share a drawer in the company's cabinet.
Purse:
-Wallet (money / credit cards / ids / discount cards / club card / gift cards)
-Keys (spare car key / house key / storage unit key)
-Bus Pass (in a card holder that I got in York, UK)
-Cell Phone
-iTouch x2 (one w/ music (32gb 2nd gen) & the other for e-books, manga & work stuff (64gb 4th gen))
-Ear-buds Headphones
-Mini-Manicure Kit (nail clippers, file, tweezers, 2 other tools that I don't use)
Work Days Extras (in my Totoro tote bag):
-Folded up Eco-Bags
-Hoody Jacket (it's F-ng cold on the bus)
-Umbrella (for those rainy days/nights)
-Book
