I just heard about Office Lens. Can Office Lens be used on the Surface Pro 3? If so, is it a part of MS Office. I have a home version of MS Office but can't find it. I've been to the store and do not see it as an app to download. Can someone explain it a little? I know what it is and does. I just need to know where it is and how to access it? I'm beginning to think it's just for Windows Phone.
