Then how did Maemo 6 go from flagship OS as OPK had stated it would be to low-level as Meltemi? There's more to that than folks are paying heed to... Meltemi will be much lesser than Harmattan to accomplish that goal.
...OPK had years to deliver a coherent plan. It never happened. Microsoft was able to step in because of Nokia inability to produce results. I do not see it any other way. The results, the high return and defect rate, Qt just now becoming good enough and entrenched enough to be a good thing, all are years after the fact. Nokia didn't have years to get things ready.
