Nokia just wants to spend as little as possible to fulfill their obligations to Intel. The n950 was a device set to be distributed in 2010, that they decided to nix for various reasons, but had already produced units. Since hardware wise they are close enough for development of N9 apps, why waste money giving N9 to developers, when you have existing hardware that is unusable to sell to consumers, but fine for developers of a platform you don't want to spend much money on.
