That's true. Nokia won't survive in an Android world if they have long product cycles. Like Sony Ericsson, who still pumps out Android 1.6 phones to this day because they can't move fast enough, in contrast to Huawei or HTC, who are quickly moving phone designs to the latest Android OS.
As for Motorola, they're not going to pretend they know software, so they're not, and so they're going with Android.
On the other hand, Samsung is pushing its Bada, and the Wave handset has sold at least 3 million. Not as good as the Galaxy S with 5 million, but that's still a tremendous success for Samsung and they're following the initial Wave with a second Wave of three handsets. Samsung has no problem pushing Androids and Windows Phone even when they're pushing Bada.
Why? Because I view Samsung's Androids and Windows Phones to be market Trojans. Samsung might be using the experience gained on Android and Windows Phone to better their own Bada platform. Who is to say the money they made making those Android and Windows Phones will help go funding their Bada efforts?
So why can't Nokia be this way? if Nokia had been selling Androids since last year, the money that is going to HTC, Motorola, Samsung and Sony Ericsson's pockets are going to Nokia's. Hundreds of millions, if not billions of dollars, that could be used to fund Symbian, Meego, and other services. Money that is denied from their competitors weaken their competitors. Chinese has a saying, "keep your friends close, and your enemies even closer..."
Again its all business. Managers and executives are hired to mind the bottom line, not to defend a platform theology. And then again, I feel that Nokia is now too deep down a road and its too late to commit to an Android handset now. i think the company requires some serious re-organizational changes first so you don't introduce models that fit last year into this year. Need to reduce the bureaucracy so product development is much faster and more responsive to market changes. They need to overhaul an entire smug and conservative culture within.
