The pen can be kept in the pen loop in the spine, there is enough room for a mouse and at a push I can fit the power supply in too, useful if I’m going away for a few days. Generally though its just the Surface and the pen. Its protected from the elements and from accidental drops, getting the Surface from home to work.
Saying that it’s definitely showing it’s age now with the black coating wearing off at the charge point and some of the edges.
I was just wondering what everyone else used to transport and protect their devices.
