Apologies, I didn't get chance to read through all 5 pages of the responses but my two penneth is......
 
Sonar is a fantastic product and I love it to bits but we are in the minority trying to support it.  I work everyday in professional studio environoments and the only session files I am ever presented are:
 
1) Protools
2) Logic
3) Cubase
 
In fact I'd go so far as to say I have never ever been presented a Sonar CWB in my life (dont be picky about the file extension).  Simple fact is most people consider MAC's as the platform to do audio on and Protools is inherent in it's legacy. All singin all dancing Logic is $150 and for the few cross platform stragglers Cubase offers all you will need.
 
I love sonar I think its a fantastic product but I fully accept I'm trying to push water uphill with a rake in trying to convince the rest of the world this is the only platform that matters to professionals

FYI it is traditional when you are replying to a thread, you reply on the thread rather than split it on a separate thread 
Although this seems to be an entirely different topic so nevermind!

So shoot me, I'm sorry I didn't have time to read throguh 5 pages but got the gist after 2.

If I broke forum etiquette I apologise

I ate a quette once.
 
Upset my stomach it did.

I can completely corroborate the OP's experiences. It sucks but it's the reality. I'm even the only one in my professional environment who is using PC, although a few of my Mac enthused buddies are trying their first Hackintosh now which is maybe a half-win. Or a quarter win or something.

Awesome!! Another thread about stuff we can't do anything about!! 
 
I heard quettes taste like chicken.  That true, Bapu?
 
Apologies to the OP.

This doesn't actually have anything to do with the original premise of that thread. Just the same discussion that's been ongoing about Sonar for... well ever since I've been here.
 
Yeah... they probably should figure out a way to port to Mac but as a PC user I'd rather they not and just keeping making things better for ME (I'm greedy like that... lol).
 
As far as "pro" impressions within the "established" studios... I care not a whit. I heard all that crap back in the day about Sonar and it did make me hesitant to invest but really the package was too abundant for me to pass up so I took a chance. There were some hairy moments but all in all it could not have worked out better.
 
When and if I end up dealing with studios who insist on other platforms... welp, they're getting exported tracks, stems and perhaps custom VST presets if they happen to use the stuff I do. That's how I prefer to work now anyway even with Sonar users. Unless I'm sending something to a guy like Danny to double check my settings for educational purposes or to Cakewalk for a problem report I see absolutely no need to send project files to anyone.
 
I certainly don't like wrangling with other people's bundled projects either if it can be avoided. I usually start a new project anyway and drag data into it to keep things stable and consistent with how I like things set up.
 
Much ado about nuffin' IMO.

I'm a contrary sort, always have been.  I'm absolutely delighted that I'm not part of a crowd who buy hardware and software based on trendiness. It reinforces my love of the gear and DAW I use which both give me all the functionality I need.
  

I have to agree with Beep. Sonar is a great DAW. Far better then most think. I believe it can stand up against any other DAW and do very well indeed. In most cases it will run the other into the ground. 
 
I just bought Samplitude Pro X2. I had Samplitude Music Studio 2014 on my system. This gave me a head start in understanding the program.  I am happy with for what it is but Sonar is a much better DAW particularly with MIDI. Samplitude touts its object oriented editing and it does a nice job in this area but so does Sonar. CW doesn't tout objects in Sonar their term is events but its the same concept. We all know the ton of things that Sonar has so I wont compare these two.  Its a question of feel and quickness to get something done that I think matters most. In Sonar things seem simple even though they are not. In Samplitude nothing is hard but few things are as simple. 
 
I used and still have the dongle for Cubase SX1, 2 and 3. I didn't upgrade to Cubase 4 because I found I wasn't using it much. I preferred Sonar even though I had the choice. I consider Cubase an equal to Sonar on the Windows platform. Not better but different in just enough ways to make each appeal to different users. Cubase to me is fiddly. You have to set things up all the time.   
 
Where do we stand now? It couldn't be better for the end user. We have really good DAWs to choose from that emphasize one or more aspects to appeal to a broad user base. As a general DAW I give Sonar the top seat.  
 
Notice Pro Tools is not mentioned by me. I have no real experience with it. I'm sure it will do the job as well as any other. All I know about it sort of persuades me it is not my cup of tea.       

P-Theory
So shoot me, I'm sorry I didn't have time to read throguh 5 pages but got the gist after 2.

 
Must remember this technique next time I fill in my tax return....
