Personally I keep one Linux sticker on my laptop, less about expression and more a conversation starter. It's something that 99% of people won't notice but for the 1% that notices it's a nice conversation starter when everyone is bored (ie waiting at the airport)
When I next have a working laptop (I currently use a desktop and a phone), I'll probably stick on a Linux sticker and something from Discworld (probably the "Anthill Inside" sticker, intended for that purpose).
