Not that much different at all. Launching any device in the US is a tricky endeavor and it has to have the key things that folks want - social media, ease of use, plenty of apps (most go unused after the first week) and a level of popularity that means they can ask their peers questions to resolve their grievances. I'd love to say that my home market would have made a dent in what's going on with Jolla; but I truly doubt it. The US is a fickle area that only supports currently iOS or Android.
