Music software implants. I can just see it now - You'll have Firewire, midi and USB ports on your forehead and power conditioners strapped to your waist. A CD rom drive in one ear and a dvd / CDrw drive in the other.
Do you think it may ever get that far? I mean, look at chip size compared to the 70, 80 and even the 90's!
Just a thought (with no notes involved)
