"Eink devices are not (or rather, should not be) competing with the tablet that is the iPad." I'm not arguing that they should compete. Rather, I'm arguing that the iPad can be seen as having opened the door to mainstream usage and acceptance of tablets -- both as devices and as form factors. Many of the consumers who are now comfortable using tablets are more likely to use an e-ink based business tablet than they would have been if they'd never used a tablet before. And it's likely they'd never have used a tablet before if the iPad hadn't made tablets mainstream. And precisely because said tablets wouldn't compete with the iPad, those consumers might buy both. Or have one provided/subsidized by their employers.
