i still think that's too many devices.. I think need 5 maybe 6 at the most..

-High End Meego phone
-High End business class (like blackberry)
-Mid range Symbian (Like n9)
-Social Network Centric phone (like the Kin)
-Low end Symbian (Something you get for free or for 50 bucks with a contract)

I don't know why Nokia needs 16 different models. It's harder to support and more difficult to manage internally. I think part of the reason the iPhone is so polished is because that is the only phone Apple works on. Not 16 different iterations of the almost the same thing.
