The MakerBot is like the Altair 8800... It's works, most of the time, but it's complicated and slow, and it's produce is not that useful. and... what am I really supposed to do with it??
The Altair 8800 came out in 1974, but it took another ~10 years for home computers to really take off... I'm sure that in less then 10 years we'll all have some kind of 3D printer at home.
