Things to do while waiting in an airport

I'm wondering about things to do while waiting in an airport, my flight leaves soon, but these things are so boring I'm stuck to my computer. I can surf the net, but I can do that at home to. I browsed the shops looking for a gift for my wife at the duty free places, but couldn't find the cell phone she asked me about.

Any other ideas for what to do to pass the time during a layover in an airport? Thanks.

Get some good books to read! THat's what I do in the same circumstance. Also, books are great on the plane, before you know it you're landing.
