I have been using Nokia phones from s40 to s60 to Maemo for last 11 years.

Blame its past success?

Set aside management and platform's technicality. Nokia's user-friendly text-centric UI (10 years ago) used to be the key to win customers. Unforunately, it's also the same reason for its faliure (poor graphical touch UI).

Although what's happening is predicted and understandable, I am still a bit emotional.
