Surface computers (plus the Surface Dial) aren't all that's new at Microsoft's fall event. The company has quietly unveiled various Surface accessories, headlined by a Surface Ergonomic Keyboard. The wireless input device is effectively a cross between the earlier Designer Bluetooth Desktop and an ergonomic keyboard -- you get a more comfortable typing feel with quiet, low-profile keys. There's even a double-cushioned Alcantara palm rest (the same material you saw in the Signature Type Cover) that promises to be gentler on your hands even as it spruces up your desk environment. A pair of AAA batteries will power it for a full year.
