I've got no plans to move. And I'm crossing my fingers that my wife will continue to feel the same way. It'd be pretty daunting to do all of this work over again.
On the tile, the biggest factor is how the stuff is installed. For home interiors, speed is the biggest factor, so you get a series of dabs of adhesive, basically. This leaves a lot of empty space under the tiles, and this will put them in tension (as opposed to compression), and they'll be more vulnerable to cracks. Inside a house, this usually isn't a huge deal.
Interior installations are often done over joists, which introduces more opportunities for trouble.
In an industrial or commercial setting -- or a garage -- you're installing over concrete, and you 'double butter' the thinset, which means it's uniformly distributed on both the concrete slab and the underside of the tile. Without gaps in the adhesive, you get this kind of strength.
(Note: these are the cheapest floor tiles I was able to find at the Home Depot. And that's a 4-lb sledge hammer.)
