I am back in Dortmund with a couple of partners that are using these fine sunny days inside the Swyx Training room (I feel so sorry for them ;) )

The first thing I noticed when I entered my room in the hotel was a quite stylish bluetooth headset on top of the minibar. But before I could call the reseption and tell them that the guest before me had forgot this, I found out that it was something else.

Actually it was a device to open bottles! I am glad I did not try to use it, it could have ripped my ear off...
