So, I'm getting together my first Dark Heresy campaign, due to start in a couple of weeks, and I'm thinking about props.

I remember reading back on the Black Library forums (I think) about people who had used moded-up palmtops as data slates to hand out to their players. I can find some 'concept art' of what data slates might look like - that's not an issue, I'm just wondering if anyone out there has done something like this themselves, and would be willing to share some hints and tips?
