Finnish people here, please go to http://www.tosielamandiili.fi/ and give your vote for Jolla as the best startup at Slush 2012. Winning startup gets free television ad campaign on MTV3. EDIT: Actually, for non-finnish speakers: go to link above and scroll down to Jolla logo. Look underneath it for a button that says "Tykkää". Hit that. Thank you.
Apparently, the phone is coming out in December.
I don't think they aim to "sell well" in the sense that it will be a "hit". I believe they are aware that their customer base is probably relatively small and will make "exclusive" devices instead. Think Ferrari. Less quantity better quality. To a higher price of course. I would have no problem with this as long as it's a quality device.
