Although it costs a little courage to buy in an environment of Android and iPhone users with a Windows Phone, the courage will be rewarded. The result is a professional mobile phone for work. Integration with Exchange, etc. Onedrive works without problems. The killer app is Office Lens: presentations, whiteboards, documents and business cards can be super comfortable and captured land as OneNote, Word, PowerPoint or PDF on the OneDrive. Here comes the particularly high resolution of the camera to bear that even in difficult lighting conditions has sufficient reserves. Overall, it has for all professional users an appropriate app. What more 100,000 apps if I have what I need? The surface is very convenient, such as the direct linking of documents to the surface. Privately, I mostly use the camera that only in a few situations (dusk, etc.) has been unsuccessful in a full camera. Where I would have liked a little more: battery life, slot for memory card.
