Last night, in a last-minute press event, Microsoft confirmed it will retail its own Microsoft-branded Surface for Windows RT tablet and Surface for Windows 8 Pro tablet. Here is some top line info about the two devices.

The RT tablet will measure 9.3mm thick and weigh 676g (1.3 pounds). Built around all-magnesium VaporMg case, it uses an NVIDIA-made ARM chip. It also has an in-built stand, twin antennae for WiFi, and a 10.6-inch Gorilla Glass 2-covered HD display. It also has a magnetically attached cover, which doubles as a full multi-touch keyboard and trackpad.

Port wise, it has HDMI, microSD and USB 2.0. It comes with either 32GB or 64GB of storage, and Windows 8. Probably released around the time of Windows 8, Microsoft promises pricing that is "competitive" with similar ARM tablets.

The second version – Surface for Windows 8 Pro, features an Intel chip, Windows 8 Pro, USB 3.0, and a choice of either 64GB or 128GB. It has a higher 1080p resolution and comes in slightly thicker and heavier than the RT Tablet, at 13.5 mm thick and 903 grams in weight (2 pounds). Price wise, Microsoft says it will be "on par with Ultrabook-class PCs", and will be available around three months following the launch the RT model.
