In Seattle, there are espresso stands on every corner. In Boston, however, that’s not the case, at least not in the Boston Convention and Exhibition Center. While my first PAX East involved spending the majority of my time unsuccessfully looking for frothy bean-based beverages, I’m expecting this year’s festivities to go a bit more smoothly. That’s right, I’m already mentally prepared for the lack of caffeine-supplied energy jolts. I’m also physically prepared as my suitcase is currently cram-packed full of its canned, portable counterparts.
