You're about to get an all-too-blunt reminder of why crowdfunding sites shouldn't be treated like stores. Central Standard Timing has shelved its extra-thin, Kickstarter-backed CST-01 watch after running into numerous production problems. The project is nearly out of money, and the team has ditched its chosen manufacturer (Flextronics) after deciding that it wasn't a "good fit" for a small startup designing an exotic E Ink wearable. Also, the math behind the production costs simply didn't work out. CST-01's unique design was twice as expensive to build as first thought -- while you typically pledged $129 to get a watch during the crowdfunding campaign, the low part yields meant that the watch actually cost $260.
