Nokia has announced that the new N900 is now on sale in the US. It includes Linux-based Maemo platform, 32GB of storage and multiple options of connectivity including access for 3G data networks.

The N900 comes with the ability to multitask several applications or web browsers at once and allows users to surf several web pages while listening to music or while talking on instant message.

Maemo software is based on an open source platform and allows a variety of applications to be developed – from home brew to commercial and everything in between. Consumers can use drop down menus, watch flash videos and access the web on a mobile device screen, supported for Adobe Flash 9.4.

According to Nokia, the new N900 comes with a 3.5-inch touchscreen, QWERTY keyboard and enables consumers the ability to personalise up to four different home screens. It is equipped with a 5 megapixel camera, Carl Zeiss optics and a dual LED flash along the ability to share those images and videos from device to services such as Ovi Share. With Ovi services like Maps and Files, the N900 allows users access to their Ovi account.

Alessandro Lamanna, vice president of retail sales at Nokia, said: With an open source operating system, incorporated technology like an OMAP processor, and real time web widgets, the Nokia N900 delivers the experience of a pocketable computer that has the information you’re looking for right there waiting for you thanks to the ability to be connected just about anywhere.
