If by "this" you mean availability of adaptive apps, then I agree: Seems 
to me there is enough momentum - e.g. multiple vendors reusing code from 
each other, all tied to mainline Linux

Seems to me the failure is directly tied to getting code pushed 

Obviously when upstream project is dead (as is the case for QtMoko) 
there is no way to upstream - apart from taking over as upstream.  And I 
guess over-the-fence upstreams like Qt and Google can be painful to push 
changes to (e.g. require copyright assignment), but I am not familiar 
with the details of those.

Purism evidently invest in pushing code to mainline Linux and u-boot 
(and other projects higher up the stack as well).  Time will tell if 
they push enough, and if there continues to be enough momentum.

I am optimistic.
