This is a great thread. What happens when there is a problem with a manufactured home? I'd bin the iPad, do you build a new house?! Working with proprietary systems is hard and expensive.
Prefab house sounds like the big builders. Everything that can be installed is the cheapest garbage that can legally be sold. If you watch big box home retailers (home depot, etc) they even make fun of it by calling the worst possible model they sell the "contractors special" or "builders special" to emphasize that no one who intends to live there and be stuck using it, would ever install such garbage.
