Towards a Merger between Symbian and Android?

After being acquired by Nokia, Symbian is now an Open Source project, with its status the company expects to boost its development. Some analysts expect to see a merger between Symbian and Android in a near future. The main goal would be a create synergies between the OS and the common mobile platform supported by Google in order to compete with leading Windows Mobile and the quickly growing Mac OS X Mobile, the recently introduced OS powering the fast selling iPhone. The AppStore is a powerful tool for customers as well as a mean for Apple to collect money and push developers to support Mac OS X.
If the possible merger between Symbian and Android are currently most likely the fruit of expectations of some analysts, it seems that the main players are getting ready for the next war for OS Mobile dedicated to handheld devices, 20 years after the first one supposed to define a final winner for desktop and notebook OS. As in the past, Apple will be alone due to its policy for not licensing its OS X mobile. If it strongly improves the user experience by having the right OS for the right hardware, it also limits choice or alternative for end users while letting Apple alone against all the others.
If Apple can successfully repeat the strategy developed around the iPod/iTunes ecosystem with the iPhone and AppStore, it might well be imposing its model to the other main player despite being the last one to have entered the market. This might also require/imply the future release of smaller iPhone models, aka iPhone nano, which will be cheaper to manufacture/distribute and might allow Apple to extend this offer beyond the current exclusive partnership deal.
