As technology continues to get smaller and faster, buying a simple plastic pen may soon be seen like the equivalent of buying a flip-phone… Sure, you could do it but you just don’t. This is where Lernstift, the German pen that vibrates when you make a mistake comes in.

In a way, this pen reminds me of HAPIfork – the fork that vibrates when you eat too fast… These are a new class of devices designed to monitor your activities and assist you in improving your behavior.

You can preorder the pen now… It should be available this August.
