A pair of midrange smartphones wasn’t the only hardware that Microsoft unveiled at its first Mobile World Congress since finalizing the purchase of Nokia’s devices business.
The company also debuted the Universal Foldable Keyboard, a thin, portable keyboard that connects through Bluetooth to the iPhone and iPad, Android devices, and Windows Phones and tablets.
It’s a small square of a device, with a matte grey finish and a magnetic closure that keeps the two halves together. You unfold it to see a keyboard that’s split down the central folding seam. Some keys are larger than others, but they’re responsive and spring back when you type.
