Qt is one of those things that I've heard of before, but did not know was still used for mobile development today.
The monthly commercial license fee is a bit of a downer though. I feel that a lot of software development agencies (my workplace included) are just not gonna bother with it and just use something free instead.
I agree about the C++ point with you. I have to confess I'm also one of those people who generally want to do things on a higher level. Would definitely give Qt a try if it was free for commercial purposes though.
