For a long time, I just threw all of my gear into an Eastpak backpack I'd had since high school. But my laptop got all scuffy and gross like it had been hanging out in the wrong Starbucks or something, so I finally got an actual laptop bag to keep it all protected. (Also, the backpack made me feel like I was still in high school.) Now I have a couple I rotate between depending on the mission-I like Timbuk2's huge Hacker bag for trade show survival, and a smaller one for everyday. But it's messenger all the way (as it is for most of us at Giz). What do you carry all of your gear in? And what are you lugging, anyway?
