Depends on the task at hand, but my day to day load out is a trusty mechanical pencil, a notecard, and my Palm Pre. Anything i'd need to note that wouldn't fit on the notecard is long enough to be worth whipping out the phone for (which is pretty snappy, with a minimum of effort put into tweaking it). Likewise, it keeps me constantly plugged into the 'net, so I can look up any data I need on the fly. Same if I ever need access to my home machine, or to remotely administrate any of the servers I manage. With a full terminal and access to a solid optware repository, I can even write up patches to my code in vim on any machine I own through SSH without carrying around a bulky device (like the MacBook Air cough).
