The Arc'teryx Switchblade is always with me. It has more than enough room to carry a 15-inch MacBook Pro, iPad, myriad chargers, cables, GoPro, magazines, notepads, pens, spare hard drive...and that's only in the main compartment. The three other easy access compartments are perfect for everything else you'll ever need. From the neatly placed penholders to the hard drive pocket and key clip, this bag is designed with Arc'teryx's well-known attention to detail. It's a great commuter bag and travel companion, rugged and padded enough to protect everything your mobile office requires.
The Switchblade retails for $99. More info: Arcteryx.com
