The world's largest manufacturer of mobile phones will join the PC market with its Booklet 3G netbook.

世界上最大的移动电话制造商将会以其3G上网本打入个人电脑市场。

The Booklet has 3G, Bluetooth, and wi-fi connectivity

The Windows-based device is about 2cm thick and will offer 3G connectivity as well as wi-fi.

Analysts³ said the laptop was a "natural extension" of the company's product range but the firm would face stiff competition（激烈的竞争）.

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

The Booklet（小册子） has an aluminium⁴ case, weighs 1.25 kilograms (2.75 lbs) and its 10-inch screen is HD-ready.

Nokia has released a number of small, "tablet"-style internet-enabled devices in the past to mixed reviews, but this is the first effort which is claimed to be a full-function PC.

"A growing number of people want the computing⁵ power of a PC with the full benefits of mobility," said Kai Oistamo, Nokia's executive vice¹ president for devices.

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

Crowded market

The Booklet also has integrated Bluetooth, GPS, a webcam and an SD card reader. Nokia claims it has a 12-hour battery life.

But if the Booklet has an edge in the crowded netbook market, it may lie in the device's heritage（遗产，继承物）.

"Nokia now faces new and different competitors for the Booklet that are strong in the laptop PC space such as Dell, HP and Sony that are weak or non-existent players in mobile phones," wrote Forrester analyst² Ian Fogg on his blog.

Mr Fogg said the Booklet's unique selling point was an "internal mobile broadband card with a SIM slot."

"Other netbooks rely on external USB mobile broadband modems⁷ for Internet access," he wrote on his blog.

"The presence of this internal wireless⁸ modem⁶ is why the Booklet 3G is a natural extension to Nokia's traditional phone handset product range."
