Yes, the question as such is valid, was first asked in December 2013 and has been answered by Jolla representatives several times since then. From Dec. 2013 they had a very clear communication, saying that parts such as batteries will be available from the store as soon as they can provide them, but they don't know when that will be.

I'd rather have them work on the solutions than entertaining a bunch of people who never will be content, no matter what Jolla says or does. Haters gonna hate, right? (Following twitter, it's always the same three or four accounts who are destructive towards the community. I'd very much prefer Jolla's employees and managers not to waste their time on those.)
