A chromebook competitor?
I'm considering teaching, selling and supporting Chromebooks and the people using them in "old folks homes" (as we called them long, long ago) as an inexpensive and low skill entry to the internet. Some potential clients will have enough experience that they will require Windows access. If (and it is a bit hard to determine from the site) Windows machines with persistence can be created that problem is solved.
Have you looked at the issue of migration from an existing Windows home system into one of yours? Were that made relatively easy it would be a huge benefit. Perhaps a partnership with Laplink and their PCmover would benefit both you and them.
