This turned out to be quite the week for unannounced Microsoft apps. News of a "light-weight" email solution broke cover a few days ago, and today another pair of productivity apps were tipped. Thanks to @h0x0d on Twitter -- the source of the Flow email news -- we now know Microsoft is testing a cloud-based (thanks to OneDrive) clipboard tool that syncs across devices and platforms. The app is called OneClip, and though it's reportedly in internal beta. While it's available for download in the Windows Store, it'll only work for employees with the proper accounts. This means that you can copy a phone number on the desktop and have it immediately available on your Windows, iOS or Android phone.
