However, now that Microsoft has been embraced, the winning strategy for Nokia is clear: Sell only two phones.
There is huge, unmet demand in the world for a phone that does nothing but make calls. Nokia can and should design and build the ultimate minimalist, tiny, super-reliable cell phone that does not connect to the Internet. It should have the best-possible call quality, have the best antenna possible and should measure battery life in days or even weeks. Nobody cares what the operating system is.
Second, Nokia should design and build the ultimate smartphone based on Windows Phone 7. It should provide a much better call quality than the iPhone (not hard to do), have a better camera, better screen, better everything than existing smartphones.
The company should ban Symbian, MeeGo, all product forking, ugly design and the use of numbers in model names. It should embrace radical minimalism and beauty in all hardware and marketing.
In other words, Nokia should embrace the winning Apple strategy. Getting in bed with Microsoft means the Google strategy is off the table. That leaves only one winning strategy left.
