Because of my age relative to the era of computer, for a good portion of my life computers were Serious Things used for work and school. They also belonged to the family and there’s no way we could have gotten away with putting stickers on them without getting in trouble. So back in 2006 when I went to Blackhat and Defcon, for the first time I saw people’s laptops covered in stickers. The EEE PC (new at the time) had a meetup session where I saw others who’d painted their machines various colors. I’d ended up with a bunch of stickers after Blackhat and Defcon, so I decorated my first-ever laptop, an Acer.
