I guess some hobby users might be emotionally attached in the way you say, but I think you are missing a wider point. For anyone using Sonar commercially or doing anything serious with it, it represents a huge investment not just of money, but of time and familiarity. Not to mention all the projects that are now tied into Sonar that take a lot of time and effort to move to safety in another DAW where it's nearly impossible to replicate the original. These are major upheavals that are bound to make people emotional, not so much for the sad demise of Sonar, but the sad demise of their workflow and all the hassle involved. There are a lot of people affected by that. Your message comes across as being pretty cold and heartless for people having to go through this struggle and at this time of year.
You know what they say. It is not what happens to you, it is how you handle it! I am a professional user and was using 8.5 Producer at the time of the X1 debacle. I knew then I had to switch. And did so quickly and efficiently in fact. It is the more professional users in fact that will do this without emotion and get on with it. I don't know why everyone is going on about transferring projects over because as a professional in reality you actually don't. You finish projects in Sonar and that is in fact the best place to leave them. If a pro job sounds good you won't in fact have to revisit it again! I have never had to transfer a single thing over. Occasionally you might have to open something but that is why I still have 8.5 still installed and running on an older machine. The best thing to do is quickly learn the new DAW and continue with new projects on that. And if you are a pro then you can actually still do the odd project or two in your original DAW while learning the new one. This whole procedure is still not an emotional experience. It simply does not have to be. It is all about how you handle it.
Sounds like to me you are not a professional user but a hobbyist. I see the hobbyist as having the emotional response, not the professional. When professionals encounter problems they find solutions and move on. You have to.
