I'm on the other side of this "debate". I use 3 Macs and many iOS devices, among other computers.
I couldn't care less if there are some UX anomalies brought over from the port / re-write. I also couldn't care less what reviewers might think who are too dumb to understand alpha or beta code, or to understand that audio quality is going to be job #1.
The most important thing for me in the early drivers is the audio quality and overall ease of use I've come to expect from working with JRiver on Windows. I want it to deal with the Mac midi app and input bitrates automatically, and do the right thing with DAC output (like Decibel does).
I have no doubt that the team will eventually put the buttons and menus in the right place.
FWIW, as a Home Theater Computer application, the nicest Mac app I've seen to date is the totally "non-standard" XBMC. If the current version didn't sound so terrible, it would be even more widely used.
But at least I can use it from across the room without an iPad or lowering my screen reslution
Apple has not really designed this experience for the Mac yet IMO (well, outside of Apple TV, but that's not Mac-based
)
Maybe it's time for them to "think different" again
