Since you are in Germany I don't know how different it is from the version we have here in the US. With the Apps feature you can use some of your iPhone's third party apps through the BMW system via idrive. Facebook, Twitter, Pandora and BMW has their own app called BMW Connected (news, web radio, wiki local, calender, vehicle finder, last mile navigation etc.) which I think is great. I don't think it is essential, but it is nice to have. I use the web radio all the time.
