First of all, welcome to the wonderful world of Startup Weekends!
Market testing and customer validation was really emphasized at the last SW I was at. In our team, there was one member who had absolutely no technical background, but that was okay. When we'd come up with our initial idea, he helped a lot by getting out there and talking to potential customers to get a feel for what they did/n't want in a product and what they'd pay. That kind of info guides what you're building, and makes your case stronger when you're presenting!
So I'd say bring a traditional (as in paper) notebook with you, as you never know when you might be out in the field!
