The device is great in the hand, has a good size and a great display. It is very well made, solid and suitable for everyday use in all respects. You get for the low price really a huge range of features, even including NFC.
The Windows interface is the solutions of Apple and Android miles ahead. I know these devices and venture to say that no one of Windows Phone back to the "old" surfaces of Apple and Android will, if he / she has worked for several days with Windows Phone. The manual does not need one, because everything happens intuitively and naturally. The presentation is fluid and without noticeable delays, and displayed in the tiles and automatically updated information facilitating the work enormously. This is particularly true for office use where it matters in a straightforward and automatic as possible provision of information. Here has a positive effect that Windows and Windows Phone great complement.
The surface is easy to customize by changing tiles in size (3 sizes are possible), adds or removes. For example, even frequent business partner can be stored directly on the home screen, so that the path through the contacts directory deleted.
The free mapping and navigation application has great graphics and runs smoothly and stable (although the navigation function is currently still in beta status). An online connection is not required, which saves costs especially abroad. The cards and votes needed can be easily downloaded and stored in the device memory - this is true even for so voluminous cards such as the US.
The device synchronizes on request - for example, via wireless or data connection - Contacts, Calendar and messages with the Outlook.com account and other mailboxes, so that spontaneous updates of appointments "on the road" are possible - also very important for office use.
The integrated Microsoft Office software Office documents can be easily accessed and edited on your device. It can be chosen 365 as the location also Skydrive or Office. So you can go at any time to access the meantime updated documents or make yourself upgrades.
Windows Phone is fully stable. The latest firmware update took place imperceptibly in the background (via WLAN), so that I was without my help at the cutting edge.
By the way there are plenty of apps in an almost unmanageable amount for me. I've found all that I need for productive weekdays, and miss nothing.
Overall, a great device that I would buy again at any time.
