My parents used to swipe critical computer parts from my machine as punishment, to take it away. Things like power cords, keyboards -- little stuff that cripples the computer. But I had spares for days, stuffed in a little box in the back of my closet :)
Growing up, I didn't need my parents to do that. Getting an IBM PC clone to play the latest games in the 80s required a constant effort of flipping dip switches, pulling jumpers, and reseating chips. Not to mention the whole EMM/EMS thing.
I'm still figuring out what I'm going to do for my son to give him the same... incentives.
I truly consider that my kid will be able to use the internet against me in ways inimaginable. Its exciting!
