We had hoped to buy these for all our paperless office employees, and gave it up almost solely because it was far too easy to transfer files.
If they deliver a device with on-device encryption (as this claims) and sync or manual transfer tied (and locked) to company-owned storage, we'd buy them for all our Pro(fessionals).
To your point, instead we give our professionals iPad Air with Paperlike™ for pencil-feel and a keyboard for on-the-go use. We'd rather (for reasons) give them Remarkable Pros if it was capable of meeting Professional data-loss-prevention (DLP) needs.
