Basically every enterprise of a reasonable size is going to require their users to consume multimedia content of some sort - web calls, training materials etc. If the crux is that even you, clearly a passionate eink advocate, wouldn't be able to use it as a sole device then that essentially makes the market tiny. In fact, a secondary eink display sounds like exactly what you need. When the refresh is more capable it'll be more of an option, and I cannot wait for that to be the case. But it's just not feasible to sell a laptop with an eink display as yet.
