What I see from this statement is that more importantly Jolla is still a small company and they do their stuffs one step at a time (it was also a statement of Mark Dillon at the Slush conference). If they did sell in all countries (US included which is not a small one = lot more people) and added full features to their devices (like cell modem on the Tablet), they would not be able to cope with demands and support needed for customer service.

This is really the main reason IMHO since they seem already overwhelmed with what they already have on market. Just give'em some time and let them expand a bit more before asking them to be the next Apple or Samsung in term of reachability.
