As a matter of fact, its API isn't API-compatible to PyQt4:  static methods 
have different names due to restrictions in boost.python.  It also doesn't seem 
to support any of the things introduced as of PyQt 4.5 (new signal-slot API, 
implicit QVariant conversion).

Moreover, PyQt-compatibility isn't guaranteed for future releases of PySide.  
The roadmap [1] says:

For my part, I'm not really convinced, that this whole thing is going to be a 
success story.
