I’ll be honest (as always): Forget about it as daily driver at the time being. But get one. Get used to the look and feel. Play with it. Support the community by giving feedback, support Pine64 by buying one.
Really, it is fun 
.
Even more important: Get your Librem5. I’m waiting happily for it. I paid for the app crowdfounding idea by Purism and I would pay for Librem.one if they’d charge me with the optional payment for the basic account.
They pay people to make the Librem5 into your daily driver and this work also goes down to the Pinephone (the same way all the work on Mobian for the Pinephone supports the PureOS Librem5 development).
To start an ecosystem for Linux phones there need to be customers - even though if the early ones to get toys and probably pay more then the ones buying from an established market.
If it is within your financial possibilities and if you do not like to use the products of google and apple be a patient customer willing to invest into a new and evolving market.
