Nokia is allegedly working on a Windows tablet and a new image of a prototype with Nokia branding has just leaked along with some details.

Many industry watchers believe that Nokia will enter the tablet market with a slate running Windows 8, expanding it offerings beyond its Windows Phone 8 range of devices. Some reports claim the company plans on using the full desktop version of Windows 8 to power its tablets, while other rumors indicate the company plans on using Windows RT in an effort to keep the price of the tablet down. It looks like the company might have settled on Windows RT, as a Nokia-branded tablet has now leaked with that operating system apparently powering the device,

Windows Phone Central has posted images and details it allegedly obtained from a user posting the information on its forums. The back of the tablet clearly shows Nokia branding and the device is likely just a prototype. The tablet reportedly packs an NVIDIA Tegra 3 processor clocked at 1.3GHz, 2GB or RAM, an HDMI out port, a USB port, SIM slot, a 16-point multitouch screen, and Windows RT.  The tablet also uses a similar magnetic power connector, like the one found on Microsoft's Surface tablets. The source claims that Nokia dropped plans for this tablet due to its Tegra 3 chipset.

Nokia is expected to release two tablets in the near future and the company will likely swap out the processor for either an ARM, Tegra 4, or Qualcomm Snapdragon 800 chipset. The updated processors all feature faster performance and offer better battery life. Recent rumors claim the company is planning on releasing a 10.5 and 8.5-inch tablet in the near future, both allegedly featuring an aluminum case. The leaked image of the purported Nokia tablet prototype leaves room for interpretation. The case might have an aluminum back, but that information and the tablet's screen size was not disclosed.

While this prototype has reportedly been cancelled, recent rumors and the build of this alleged prototype do paint a clearer picture of what Nokia might be planning. We'll just have to wait a little longer to actually see if Nokia follows through with its latest tablet rumors.
