The security I bought because I had taken the notebook to an event and during a concert of this should be used for a beamer presentation. The notebook was added but not used. So I had left it in the lounge. We were, however, said that they love to go through strange people and the danger is great that something was stolen. The notebook I had connected to a plurality of stacked chairs and so it probably made as a deterrent to a potential thief that it would be embarrassing to have to bring a notebook and several chairs. So I could later take the notebook safely again.
How soon will I once again come into the situation take my laptop to a conference or a presentation at Puplikum I do not know. However, there is always a handy thing when you can securely connect to a bistro table, a bar or at a pinch to a radiator such a part then. Especially with events something is often taken. It's a bit sad that only notebook via a so-called Kensington Slot feature. Such a slot in beamers or mobile printers would be very smart, because then you could also connect these devices. Unfortunately, these devices too often lacking.
