ABSTRACT
As with its predecessors, my current laptop is a mystery. I can make it work, but I have no idea how it does it. I’ve never seen inside it and have only the vaguest idea of what the sleek, brushed-aluminium case contains. My interaction with it is entirely through its surfaces – screen, keyboard and outer casing. That interaction is mostly about my use of the computer, to write this chapter, send emails or browse the internet, but occasionally I give it a little maintaining attention, cleaning the fi ngermarks from its screen or wiping over the aluminium case.
