I love how open source, customization, and the Maker aesthetic is being applied to hardware now... Of course I'm not the only one. Looks like IDEO is too. They've just posted a great case study of work they did with Bug designing e-ink displays for BUG modules. Really beautiful design work, for a suite of really exciting products.
