Convergence is always a technology innovation most appreciate. The folks with the most creative and useful ideas generally land on top. Here is an example of an idea that is middle ground. The rechargeable USB lighter that doubles as USB drive.
So here is how the design works. Rather than using fuel as in traditional lighters, the USB lighter uses electric coils for sparking up. So just like a car cigarette lighter (if they even make them anymore) the electric coils recharge via USB. The convergence is where you stuff in some solid state memory so when your Kool cigarette lighter is plugged into your PC you have a logical excuse that it’s a novelty USB drive rather then broadcasting your smoking habits – although it’s the same difference I suppose.
For the decreasing number of smokers out there the design is unfortunately just that, nothing in production as of yet.
