No, I didn't apply yet. I am thinking of doing so around Dec this year for intake Sep 2011. I did a bit of research and the curriculum seems quite good, and I'm sure you'll be aware that HKUs reputation has been rising of late, so it seems like a good option, if you want to teach in HK. But if you are looking to teach in other countries you might want to consider training elsewhere. On the question of job prospects I received verbal assurance from some people that it would not be a problem, given that I'm a native English speaker, but opinion is divided on the matter. On the one hand are anecdotal stories of poor English skills among local teachers in EMI schools coupled with the general enthusiasm among parents for their children to have the best English skills possible. On the other hand is the general problem of teaching maths in a foreign language and possible resistance by school principals and staff to having maths teachers who don't speak the local language. For these reasons I'm also thinking of applying to do a PGCE in my home country (UK).
