A recent product listing at CDW indicates that Microsoft is adding a new Surface Pro tablet SKU to its existing lineup of 10.6" tablets. The new SKU ups the storage ante to a 256GB solid state drive.
The Surface Pro tablet is otherwise identical to the existing Surface Pros, however. Specifications include an Intel Core i5 3317U processor with HD 4000 graphics, 4GB of RAM, a 256GB SSD, and a 10.6" 1080p display wrapped in a magnesium chassis.
The 256GB model continues to run Windows 8 Pro, which means that users will have a bit more than 200GB to play around with after Windows, Office, and a few apps are installed.
The 256GB Surface Pro will cost $1,199.99, which means that the extra 128GB of storage comes at a $200 premium over the existing 128GB Surface Pro ($999.99).
Personally I find the Surface Pro to be too expensive for my taste, especially when $1,200 does not even get me a physical keyboard. I would rather grab one of those Windows 8 convertible tablets I've covered recently. On the other hand, if you are using the Surface Pro for business and you need as much built-in storage as possible, at least the new Surface Pro SKU with 256GB SSD is an option now.
