I hope step 5 is making this world a better place. Step 4 was clearly hardware Nirvana.

But more seriously what are is missing in the platform?
-RAD development (Qt and pyside/scripting/java such things)
-Ability to scale down to have cheaper phones also running maemo?
-Platform API stability?
-Sandboxes?
-Many users?(but this is hopefully Fixed in Frematle )
