Look at the Nokia line up of phones.
Now look at the blackberry line up of phones.
Now look at the apple line up of phones.

Notice a pattern?

Apple has one phone, they concentrate on that phone and make it smooth user friendly and easy to use.
Blackberry has a smaller list of phones they run a unified OS across all of them. They are coming out with new phones all the time but they incremental upgrades to current models.

Nokia on the other hand has been all over the place they have different platforms different handsets they kill one and replace it with a brand new model that is totally new. Developers are scattered. Over all the sum of the market share was good but because it was so scattered it was not dominate in any one area.

I can see a long term plan hatching at Nokia now with a unified platform core, instead of a shotgun approach to everything mobile it is becoming more focused.

The big question now is it too little too late.
If they fire this CEO and shift gears now I see no way for Nokia to ever make it back to the top.
