I initially preordered a Thing-O-Matic, but was quickly warned off while waiting for it to cancel and get one of the many great RepRap kits available. I'm glad I did. Anyone that spent more than an hour or two a week trying to 3D print stuff quickly came to realize that MakerBot printers were to be avoided. They cost more and were less capable than most of the alternatives. When people can 3D-print their own custom designs and thereby rapidly improve existing 3D printer designs, mass-producing printers on a long product life cycle is a losing proposition.
As far as I can tell they only got as far as they did on Bre Pettis' cult of personality and hype.
While Thingiverse is handy it is/was also subject to their whims and censorship, and they blocked any weapons or weapon parts from being uploaded there, highlighting the need for other methods of sharing 3D printing designs.
All I can say in conclusion is good riddance to MakerBot, long live 3D printing.
