Yeah I see the Neo900 and Jolla device as quite complementary and if possible one should get both.

Eeach of them has its upsides and downsides, but all in both projects can help each other, even if indirectly by providing a true Linux based mobile alternative to the current platforms.

Also even though there are architectonic differences, both should be quite compatible (no botched libc like on Android; have DBUS, Qt, Python, ...) so stuff ported/developed for one of them should be quite easily ported to the other.
