Sling the Timbuk2 Catapult Messenger Bag over your shoulder and ditch your backpack at home. You're far too 'with it' to carry something with TWO straps. Tough ballistic nylon ensures that this bag will stick around as long as the taxidermy statue in your living room (... ummm?), and the internal padded sleeve was sized precisely for your touch-screen tablet computer. Stash a light jacket and some peripherals inside the main compartment and get on pedaling down to the coffee shop before you miss double-espresso-chai-shot happy hour.
