Microsoft-Universal-Foldable-Keyboard-openAndroid? iOS? Windows? Microsoft doesn’t care. Or, at least, its newly announced foldable keyboard doesn’t.

The company today unveiled the Microsoft Universal Foldable Keyboard, a $99.95 device designed to replace on-screen keyboards on smartphones and tablets. The five-millimeter thick, full-sized keyset folds in half and can be paired “with any combination of two compatible devices,” allowing switching between them “with one touch.”

Open the keyboard, it connects. Close the keyboard, it shuts down.

Unfolded, it’s just under a foot wide (11.6″) and 4.9″ tall, weighing in at less than half a pound (7.1 ounces).

A built-in battery is said to last up to three months on a single charge, and the keyboard supports Bluetooth 4.0 on Windows 8/8.1, Apple iOS7 and Android 4.3 devices or later.

From apps to services, Microsoft has been on a “universal” and cross-platform tear lately, from Office apps to Microsoft Garage releases.

Microsoft says the Universal Foldable Keyboard will be available in July.
