I feel like I'm in a game and I'm running around trying to find a power pack or something. Conference centers need to start thinking about this: What do you do when you have 200 people show up and they all have laptops? Sure there's wireless, but where do I plug in for some DC juice.
Note to self: Start packing a power-strip/extension cord so you don't have to sit on the floor on the side of the room to get power.
