It's a company of 80 people taking care of the whole smartphone manufacturing process (hardware, software, selling, etc). Not 80k, not 8k, just 80. Do you have any idea of what this entails?

I don't, because there is currently no company with the same core business (Tizen/Samsung is clearly not production-ready yet). Yes, they should improve communication, but just remember first version of Android, and consider that they had all the human and financial power of Google behind it. Despite the resources, Android as OS sucked for the first 2 years.

Jolla is clearly making mistakes on the selling part. However it is also something they can quickly and easily fix in a near future.
