I completely agree with Lurkette... and further to my point, as it becomes easier to do (cheap and pain free) there will be more and frequent body mods.
I like the future that William Gibson painted in his short story
Johnny Mnemonic, where gangs like the Lo Teks completely differentiate themselves from the mainstream by radically altering their bodies in a visually low tech fashion (as opposed to those who do so in a high tech and societally acceptable fashion).
