Wow, this is so unfair to them. I followed the project with intense interest from day 1, and "Feels like they more or less took the money and called it quits" is total BS.
To be clear, I think the original ZPM gang got in waaaay over their heads - one of the biggest problems is that the kickstarter was just far too successful: the ZPM team had to go from building a prototype to actually worrying about how they were going to manufacture these at a sizable scale. I think it's totally fair to say they handled things quite poorly as it became clear they were struggling, and if I were a backer left with very little to show for it I'd probably be mad, too, but to say "they more or less took the money and called it quits" is not, at all, what happened.
