I don't know what you mean by "ecosystem", nor do I know what Jolla is up to. But I know what the ecosystem that I want, no, that I need is: the internet. I don't want one app store only, I want community repositories, debs, sources. I don't want one PC application that takes care of syncing, I want standards like USB and Bluetooth to just work between any device and my smartphone. I don't want to subscribe to yet another so-called cloud service to host my pictures or contacts, I want to continue using those that already work for me.

After all, that's what smartphones are all about. The other thing, the device that comes with its own ecosystem and forces the consumer into this trap, is not a smartphone.
