Well, I'm piecing things together a little at a time.<br><br>I have a PC backpack for commuting to-and-from the office. It has some stuff like bad-aids, a multi-tool, tape, paper, water bottle, etc.. But I wanted somethings I could caerry with me at all times, including meetings.<br><br>I have a Palm Pilot in a small leather valise case that zips shut. It's 6 1/2" tall x 4" wide by 1 1/2' thick. The right side holds the PDA via a vacro strip. It also hase a pen ho;der and stylis holder. My stylis also has a pen tip by unscrewing the pointer tip. The left side has a flap that holds 3"x5" iindex cards or paper. I cut paper down since I can carry more sheets, but I do have a card on the bottom of the "deck." The flap opens up to reveal 5 slots/pockets for holding business crads. Three of them actually hold business cards, two from meetings with contacts. One holds business cards I made up for my scout troop. The other two hold a grafetti cheat sheet for the PDA and the last holds a copy of my PSK cheatsheet. It's not truly appropriate in an urban setting so I really should include a different sheet (someday). One of these slots is where I'll place the SpyderCard knife, plain blade, BTW. (Thanks everyone for your suggestions).<br><br>Under the flap, on the case's inside cover, is a small business card pocket where I actually keep my business cards .<br><br>When opened, the flap has an isnide pocket between the 3"x5" side and the 5 slot card side. In here I've stashed a small plastic sewing kit case (2 1/2"x4"). It includes a small sewing kit (surprise!), 2 quarters & an exacto razor blade taped to a business card, another copy of my PSK Cheetsheet and some band-aids.<br><br>I added a split rin on to the zipper pull tab. It's the removable type where you can detatch the keys. On this I've added a Fox whistle and Photon II LED light. I find having the Phjoton detaychable is useful as I end up under desks occaisionally when my coworkers ask for me to see what's wrong with their PC (before they call the help desk). The first thing I do is o make sure everything's plugged in (power, network connectiion, etc.)<br><br>Anyway, I know there's more I can add and I will. What I like is that it's mostly inconspicious, except for the bright orange whistle, which folks in meetings will occaisionally ask me about. That give me an opportunity to explain why I have it, to which the usual response is "I know who to look for in an emergeny."<br><br>So what else should I consider?
