An estimated 50,000 people worldwide can label themselves digital nomads. Laptops and fast internet liberate them from office confines. But many still want professional surroundings, so they rent spots in what are known as coworking spaces - KoHub, for example, on the island of Ko Lanta in Thailand. A work station here costs about 140 euros a month. It's easier to get things done in like-minded company. And, after work, a tropical paradise awaits right outside the door.
