Remote workers, multicontinental teams, crowdsourced projects -- there are a lot of reasons to use collaboration tools, but few that are built around stylus or pen input. Microsoft has been teasing its own Whiteboard app for some time, and a public preview is now available.

Back in May, Microsoft showed off a tiny bit of Whiteboard and other stylus-friendly Office updates while talking about the latest Surface Pro updates. The just-released app promises to be a collaborative tool for real-time sharing of drawings, photos, graphs and more, not just for Surface products, but any Windows 10 system.
