What's inside your bag, briefcase, backpack, purse or man-purse?

iPhone 4S on AT&T, no case. Essential apps include Weebly's new app, the Gmail app, Greplin, YouMail, NewsRack, news:yc, Uber, TripIt, CardMunch, Softphone, and the rest of the usual suspects.

Fourth-generation Kindle (Wi-Fi) and iPad 2, Wi-Fi only. These days, my iPad is primarily used for the Luminair app, which controls DMX-based lighting systems over Wi-Fi using a protocol called Art-net. Macbook Air.

STM Bags Alley small messenger bag.

Sprint 4G mobile hotspot, iPhone charging cable, Macbook Air ethernet adapter, Bose QC15 noise-canceling headphones (comfortable and great for traveling), 3 AAA batteries, Glif iPhone stand, RFID security access card, and an Olympus PEN E-PL2 camera with the Panasonic LUMIX G 20mm f/1.7 pancake lens--the other lenses stay at home.
