Microsoft not only just announced one Surface tablet but also announced one for the consumers who require tablet with more grunt in terms of hardware – the Surface for Windows 8 Pro, which is slightly larger and is Intel-based(3rd Generation Ivy Bridge) than its ARM-fueled counterpart for Windows RT.
In addition to the more full-fledged OS, it packs a larger 42 W-h battery, an Ivy Bridge Core i5 processor (at least in the model on display),USB 3.0 ports instead of 2.0, and your choice of 64GB or 128GB of storage (double the standard offerings of the RT Surface).
You’ll also get a higher 1080p resolution from the 10.6-inch ClearType display, but it comes wrapped in a package that’s 13.5 mm thick and weighs 903 grams (compared to just 9.3 mm and 676 grams for the RT). It also has some cover called the Type cover compared to the Touch cover of Windows RT one and hasa accessory of its own: a pen with “Palm Block.” As for pricing and availability nothing much told clearly,but Microsoft is only going as far to say that it will be “on par with Ultrabook-class PCs” and available about three months after the Windows 8 launch (when the RT model will be available).
