Details on the Pro variety of Microsoft's Surface tablet have been hard to come by since the company first announced it back in June, but it's filled in some big ones today. It's confirmed in a blog post that the device will start at $899 for the 64GB model, with the 128GB version setting you back $999. Both of those are what's Microsoft's dubbing the "standalone" model, which means you'll get a Surface pen/stylus, but have to shell out extra for a Touch or Type Cover (each over $100). Both will be available in January, although there's no specific date or word on pre-orders yet.

As you can see, the device looks similar to the Surface RT, including the same "VaporMg" casing and built-in kickstand, and it also boasts a 10.6-inch display with a 16:9 aspect ratio. A key difference with that latter bit, though, is that the screen packs a full 1920 x 1080 resolution as opposed to the 1366 x 768 found on the RT model. You'll also get a third-gen Core i5 processor with Intel HD Graphics 4000 (no more specifics on that just yet), 4GB of RAM, a Mini DisplayPort that can output a 2560 x 1440 resolution, a full-size USB 3.0 port and, of course, Windows 8 Pro with support for all your traditional desktop applications. All that expectedly makes the tablet itself a bit heftier than its RT-based counterpart -- it's just over half-an-inch thick and weighs in at two pounds on the nose.

Update: The spec list confirmed that the Surface Pro will have a 42 W-h battery, but Microsoft has now also expanded on that in a tweet, saying that the device is expected to "have approximately half the battery life of Surface with Windows RT." Based on our testing of the RT version, that should translate to just over four-and-a-half hours.
