I've even run Poser on a netbook, so a laptop should not be an issue. Screen size is pitiful, so it would have to be hooked up to an external monitor. I haven't rendered anything of significance on it, but it ought to be slow compared to a regular laptop or desktop. The netbook does have a very spacious 160gb hard drive. It's not my computer of choice for doing Poser renders, but it's great for laying out stuff and playing around with Poser content when I'm away from home.
