The biggest problem for nokia is that a lot of stuff clearly just isn't finished or in a transitional state. Some examples:

-The N8 ships with an old version of Qt (no QML and no OpenGL)
-the UI of Symbian^3 is still very much menu based (like original symbian)
-the N9 is delayed to next year
-N9 will be based on the older maemo base (renamed MeeGo)
-the Nokia Qt SDK on Linux doesn't support Symbian yet
-the Nokia Qt SDK is still Qt 4.6 based ( no QML etc.)
-the Nokia supported PySide Qt binding are still in beta

Getting a new CEO with software experience seems a good thing since these are software development related. Will it be better for Nokia to abandon the software development and switch to google or microsoft software? Difficult to say, also becaus a lot of stuff isn't finished. But since Nokia does make money they can effort to finish the current plans and evaluate afterwards. If it isn't successful then they can still switch strategy.
