I refuse to buy clothing without pockets. (Well, for regular every day stuff.) This limits my choices a lot, but y'know, working geek.

I do not want to haul even a small shoulder bag with me when I'm wandering off to fix a computer somewhere (and I often do want my phone - both for something to read while it's booting/rebooting, and to take pictures of long error messages.) And I have to have my work key, no matter what else, and sometimes a USB drive, and I hate the little coil things that people put around their wrists.
