Apple vs. Nokia developer support
What the author of this analysis seems to forget, is the fact that developers are EAGER to develop software for the iPhone, even to the extent that they're willing to pay money for the "right" to develop software.
Nokia, on the other hand, has to pay/bribe developers into developing software for they S60 platform. Symbian isn't sexy.
Oh, by the way. How many people know about - or have ever used - Nokia Software Market? You know, the place where you can buy software for your Nokia phone? Seems nobody knows about that service, even though it's been available for a lot of years and applicable for more than a billion phones...
