Not necessarily true with smartphones. I just tried it out. The site acknowledges it tested out ~6M devices so far. It's not that big of a number actually. My browser turned out to be unique even though I'm using a pretty common method (basically just run Chrome on an Android). I've sent the version of Android (which was falsely detected because I upgraded to a newer version, but I'm still sending the info about the older version, so I'm assuming this is a bug), my Android model (and build) and my timezone. Anyone who bought the same model from my country (and possibly even the surrounding countries) would probably get the same fingerprint (unless he's using a different browser).
