Replacing All of Those Pesky Power Adapters?

bobrobins asks: "I'm sitting in a hotel with a desk full of chargers: laptop, mobile phone, walkman, camera, electric razor in the bathroom, and a laptop supply for the plane, oh and one for the new sony speakers. Before you say too much I've been on the road for a long time and need them all! There must be more gadget geeks out there with a better solution, really all i need is a single charger/power supply that can charge all of these maybe 2 at a time. Any ideas appreciated - my back hurts from lugging this lot around!"
