Nokia, the world's largest manufacturer of mobile phones, made its official debut into the PC market on Monday.

Called the Nokia Booklet 3G, the long-rumored device features a 10-inch screen, weighs 2.75 pounds, runs Windows, and can connect to Wi-Fi as well as to cellular wireless networks.

Nokia didn't reveal pricing details, but the device appears to be a high-end version of netbook computers that have become popular because of their mobility and low price tags.

Analysts said the laptop was a natural extension of the company's product range but the firm would face stiff competition.

Nokia will release price and availability information at an event in Stuttgart on 2 September.

A growing number of people want the computing power of a PC with the full benefits of mobility, said Kai Oistamo, Nokia's executive vice president for devices.

We are in the business of connecting people and the Nokia Booklet 3G is a natural evolution for us.
