My 3Doodler should finally arrive this week and I have to say I am looking forward to it. I agree that the name "3D printer" is questionable (it is like calling a pen a "handheld 2D printer") but I literally just want to play with it and focus on what it can do.
That said, I think that the kids segment can be (like fashion and food) a gateway to the mainstream for 3DP.
I am mostly interested in food 3D printing which I follow at @foodfabbing.
