Lenovo C930 yoga did this much better years ago with a windows machine. It failed mainly due to lack of light on the e-ink display (imho) which meant you could not type in poor lighting. I think this type of device should use the latest and greatest front lit color e-ink now. android would be OK, but those bezels? puhlease.
