Sales of smartphones are expected to overtake those of laptops in the next 12 to 18 months as the mobile phone completes its transition from voice communications device to multimedia computer.

And for the first time the rhetoric of companies like Nokia, Samsung and Motorola, who have boasted of putting a multimedia computer in your pocket, no longer seems far fetched.

"Converged devices are always with you and always connected," said Olli-Pekka Kallasvuo, Nokia chief executive at last week's Mobile World Congress in Barcelona.
