All the ICs are on tenth of an inch centers. We do all our prototyping on tenth of an inch centers using wire wrap, we don't transition the design to surface mount PCBs until we get something we like. After it's on a PCB, we "dead bug" any necessary mods onto the board using hot glue. Obviously though, we don't ship dead bugged PCBs to the customer. We use ORCad for our designs, but only a couple of us have the licenses required for the actual PCB layout.
