Those looking for productivity and Adminstrierbarkeit in corporate networks, is served here inexpensive. As a communications center for me as a user sufficient. Have both a 920s and a 820 in favor of the compact form factor again issued. Of course I edit any Office documents on the phone. But with OneDrive and BoxCryptor (for encrypted storing my data), I always have access to the corporate network and can watch in my documents. As with Navi "Here Drive" with cigarette lighter power supply and bracket for my occasional car trips super! I also do not play! Overall, it's a little slow. Now I have pre-ordered the Lumia 640. The new generation offers me considerable added value by 1GB of RAM, a very good camera, LTE, etc. for just 179, - Euro.
