meizu runs on a similar core that wp7 runs on. And you better believe many apps for ce 5.2 have been ported (keyboards, games, programs)
I don't think the lack of backward compatibility will impede me. What does is the biggest gain windows phone has over apple and its ability to do anything conceivable if you have knowledge. To what extent can phones be modified or even tweaked to improve performance? Well I think it looks like we have to wait for xda developers for an answer to that
