The switch to the NT core will replace CE. So the fact that a phone is currently running CE is irrelevant, that's the point. It's like suggesting that I need to buy a new PC to install a new OS like Ubuntu 12 (Linux kernel) because my current one has Windows 7 (Windows NT4) installed. Why? it can replace it.

The only possible reason that would be true is if the new Linux kernel and driver developers did not bother to support my older hardware as they deemed it as not worth it.

I've also just come to the realisation that I have wasted way too much time on this thread.
