They have done awesome job but the Jolla Phone is old (and was low-end even when it was published compared to its price) and their tablet crowdsourcing project suffered quite badly as they lost some other funding for a moment and their device manufacturers sold the devices elsewhere as Android devices.

Basically Jolla has promised to refund the crowdsourcing funds within this year, but still it was big setback for the project. I've tested the tablet and it was surprisingly solid in H/W and S/W sense. Just hoping they'll survive and can get meaningful market share somehow. Kudos to them anyway.
