not really, look how quickly blackberry and android shot up. Nokia has the advantage of being well known, well respected, they've been in the game a long time and their devices get a lot of attention. A new OS on the scene will shake things up. Lots of people go to Android because they don't want an iPhone but think Android is the only smartphone alternative. Nokia's comeback could change that pretty quickly if orchestrated properly. They have the funds, name, advertising avenues and build quality to rapidly get back in the running. Remember, Apple changed the smartphone outlook with one device and no mobile phone name, Blackberry went from an email device to a big name amongst young users and Android rapidly came from nowhere - Nokia is already world number 1, a massive advantage. If a device as incredible as the N900 gets little promotion, consider how incredible future devices they do promote could potentially be. iOS hasn't advanced, Android is a market flooder, if they want to, Nokias can adjust the whole landscape like they have so many times before
