Valid concerns, but as generation of clean energy increases year on year and the performance over power consumption increases I don't think this is much of an issue.

I can understand your disappointment with Jolla, the financial difficulties they had previously. I know they try very hard to keep everyone happy with what limited resources they have. This project isn't a Jolla project, it is a new endeavor, there is no hardware manufacturer to impede Zippers' progress, like there was with the Jolla 1 and tablet projects, which cost the company so much in time, resources and money.

We are working with known factors, the Xperia program from Jolla has so far been a success and is working beautifully as I understand it. You have to remember Zipper is delivering a software solution, utilizing modern hardware which is already available. Developing APKs and RPMs to run on normal devices and tailoring builds for the Xperia to prove that it is possible to build a hardware wallet with adequate security to bring blockchain markets to the day-to-day mobile user.

Jolla's involvement will be to help build this vision, as they have the expertise in the hardware adaptations and platform parts Zipper needs.
