As we are discussing the coming update and the release dates - I always had the feeling that Jolla should be able to update certain core applications separately from the system - e.g. Mail, People or Maps. Also some other components as well. So why wait for OS release? Update the application as fast as possible.
Also people around are speaking about waiting ensures release "not being buggy", "perfect release" etc. - there is NO such option! It will ALWAYS have issues and room for optimization. In the current state of Jolla(the device) it is hard to accept delays as many issues are really nasty. It is not like "desperately needing folders in launcher". I refer here to random reboots&shutdowns, numerous connection issues and missing core functions. Many of these make the device unusable for large number of early adopters.
Do not take this as a rant, but just as a questions being asked and needing more explanation.
And thanks to @w00t for the answers he spends time to give here!
