Nokia is preparing to back Windows RT by launching a 10.1-inch tablet soon. Sources familiar with Nokia's plans have revealed to The Verge that the tablet, codenamed Sirius, will be launched shortly. While prototype pictures of the device leaked earlier this month, we understand that the final design more closely resembles Nokia's Lumia Windows Phone products.

We're told that Nokia's tablet will be thinner than the current iPad, and lighter at just over a pound in weight. The body of the device will be colored, and Nokia plans to include a 6-megapixel camera at the rear with a 2-megapixel shooter at the front. The 10.1-inch display that Nokia is planning to use will run at 1920 x 1080 resolution, and has been improved for outdoor readability thanks to a high amount of bright output. Sources have also revealed that the tablet will feature Qualcomm's quad-core Snapdragon 800 processor alongside 2GB of RAM. We understand Nokia is aiming for 10 hours of solid battery life with LTE connectivity. Other features include a microSD port to extend the 32GB of storage, a Micro HDMI connector, and a Micro USB port.

Priced similar to Apple's iPad

Nokia is also planning to ship a keyboard accessory with its "Sirius" tablet that includes a battery for additional charging. Other optional accessories will also be made available at launch. We're told Nokia's tablet will be priced comparatively with Apple's iPad, and that the company won't try to undercut pricing initially. Nokia will unveil the tablet at a launch event in New York, which is currently scheduled for September 26th. The Finnish smartphone maker is also planning a "Bandit" 6-inch Windows Phone device that will be made available later this year.
