The problem is, the toy is seemingly imperfect and pretty simple, and yet it's gotten a ton of praise, and a ton of money. Some of the rest of the world then gets mad because they didn't think of and capitalize on this seemingly simple venture first.
Seriously?
Which is exactly what has happened here on two counts -
1) it is not a world first - http://www.thingiverse.com/thing:4156
2) it is not a 3D printing pen, it's just an extruder - exactly the same mechanism as that used in a glue gun.
2. Extrusion is the mechanism through which most 3D printing works. In this case, the extruder is attached to your arm rather than to a machine.
It is exactly this kind of overreaction that I was addressing in my original comment. You make these wild assumptions that it's only going to cost them pennies per unit to manufacture and that they're ripping people off. But that's far from reality.
