I basically never applied a sticker to any laptop I owned until I got a Framework. Just hoarded them like a dragon sitting on his pile of sticker-gold.
Finally figured hey, I might have this laptop more than a single upgrade cycle... it's worth burning a weird sticker or two.
I still try and buck the trend a little--instead of advertising technologies or something, my general goal is that, at first glance, nobody would question anything or think it looks unlike any other developer laptop, but that anyone paying attention will instead be met with a fractal of confusion. E.g., one on there is a "STOP, DROP, AND ROLL" fire safety sticker. In Quebecois French. From a small town volunteer fire department.
I consider it sort of a personal art project and have fun trying to collect up the most "wait, what?" stickers I can.
