Microsoft Thursday released a bit more information about the price of its upcoming Surface tablet that runs a full version of Windows 8 Pro.

The company posted on its Web site that the tablet will start at $899 and will be coming in January 2013. The starting model will have 64 GB of storage, while a $999 model will have 128 GB of storage.

That puts the device more in the price range of ultra-portable laptops than with other tablets — making it clear that Microsoft is taking aim at consumers who want to replace their computers with something a little lighter. The Windows 8 Pro version of the device will run all current Windows 7 applications, meaning that the tablet can also function as an ultra-light personal computer.

In addition to having the full Windows 8 Pro operating system, the next model of the Surface will have other key differences from the RT version already on store shelves.
