The only small issue that I ran into was during the installation process if one clicks "Finish" while the process is still creating the default App VMs then it will produce a failure message. I went back and forth between the screens and continued to appear as though the entire installation process was botched because a VM had already been created. I was prepared to reinstall and then it suddenly let me continue. I'd suggest disabling the Finish button until that process has been completed. I'm straight onto the Qubes forum here after getting up and running so I can't say if everything works.
