Headed to Belgium in the near future? Frankly, we'd recommend doing two things -- not relying too heavily on the start-and-stop Brussels metro system, and stopping by the upcoming Interieur Biennale. There, you'll find Bram Boo's salsa tablet, a four-seat contraption that's designed to hold a four-pack of eager-to-learn students that can't wait to get their greasy paws on a tablet. The mockup has four of Apple's iPads, but obviously any 'ole touchscreen slate would do. It's hard to say how well this would work for collaborative efforts, but one's thing for certain -- it'd bring back note passing in a big way.
