Everybody I know having Macbook Pros, have told about having this problem at some point, most of them several times. Sometimes they started working after some days but mostly they had to take them to the service.

City has failed to provide enough housing for incoming people. There is for example an old unused airport (Tempelhof) standing empy at prime location.

It's not empty. It's an enormous, unique, and beloved park that is starting to become as major an icon of Berlin as the Fernsehturm.

Demo on their site seems quite promising, have anybody tried this?

I once played around with it, seemed pretty cool indeed. But i guess it can still do much better when they have more data for training.
