Cellphone giant Nokia showed off its first netbook on Tuesday and announced that it would go on sale at Best Buy and would connect to the Web using AT&T’s network.

John Hwang, general manger for Nokia’s brand new connected computers division was coy about discussing future plans for Nokia computing products except to say that “there are other products in the works.”

Hwang said he would look at all options for future products when asked whether Nokia, currently using the Microsoft Windows 7 operating system,  would consider making netbooks using other technologies such as systems from Google, a rival in the cellphone world.

“We certainly wouldn’t rule out other technologies,” the executive said. Unlike in the cellphone market where Nokia has to protect its leadership position, the Finnish giant will have to be more open-minded in computing, he said. “As a newcomer we’re trying to take a different attitude.”

Here are some short video demonstrations of the product. The company is betting that the device’s slim form and 12-hour battery life will give it a good start in the computing market.

Nokia has also set up the device to easily synch services such as texting and photos with its cellphones using its Ovi service.
