Ill give it a shot:
Current book, current magazine, clipboard, Sigg water bottle, moleskine notebook(for scribbling blog entries), Rhodia pad( from when I was a student last year, still use to draft letters etc), pen roll with fountain pens highlighter, mechanical pen and sharpie, sunglasses, sunglasses cleaning stuff, stress ball, steel ruler, phone charger, thumb drive with lanyard, hand sanitizer, medications, moo cards, nail scissors etc, jewellers loupe.
That's a purse, you need a girl friend to carry that stuff. Nail scissors? Really?
