Except, if it did not achieve your expectations. Note the article is short on facts, high on marketing verbiage. If I'm not mistaken this is the same blogger, Alex Soto who previously made a lot of claims and when I challenged him on it, rapidly backtracked. Same guy previously claimed that E-Ink was a patent abuser, and another similarly named guy who headed some kickstarter program claimed E-Ink was suppressing his business and that was why he wasn't able to deliver on previous products, but when I asked him to substantiate it, he changed his blog post.
