Well obviously comparing an iPod to a home is stupid in the first place. An iPod is a consumer product, where a home is a fundamental life component. Most people evaluate a home in terms of size, location, and cost alone. People will move into a dump if it's the right size, location, and cost. In other words, people have been happily living in Creative Nomads for centuries and this "iPod" home is not going to disrupt that in any way at all.
The modular home does not innovate in the way an iPod uncovered a new consumer market. It does not exercise a cost advantage, or size advantage, nor does it out-compete a double-wide in terms of locatability.
It's really just a stylistic advantage that wealthy people will find appealing. So putting "ONLY $50k" in the headline is misleading as that is not the real story here.
