MeeGo has evolved from Maemo5, hence sometimes called Maemo6 !
MeeGo Harmattan is a shell around Maemo5/6, no more no less.

Meego (Harmattan) is not dead, we have Inception and the community will let it evolve further, like with the N900 and SSU.

People who say otherwise, know nothing about Linux and it's development !

Anyway(s) a smart phone lasts ~2 years in the ecosystem after that the new hardware sold is much better: Moore's law.
So who cares ?
Though..... my N95 stil works perfectly, now 5 years old !! (april 2007).
