Our Killer Apps list continues to inspire conversation, much of it missing the point that I'm not saying a Killer App is necessarily a good app: only that it appeared at the right time, with the right functionality or appearance thereof, to drive users' platform choices. No more, no less.
But killer apps are nothing compared to killer toys. Personally, I think that concern about toy safety can easily be overdone. Have you tried to buy a real chemistry set lately? But some of these blasts from the past are beyond even my high threshold of healthy fun.
Have a safe and happy holiday.
