I have also been with Cakewalk since the beginning. I have never purchased, used or desired any other DAW.
It's come a long way and they are doing an outstanding job with this new model. I am one of those customers who will be more than pleased to renew my subscription because I DO see a great value in it.
Conversely, BMOG, if you don't see any benefit to renewing and are happy with all of the tools presently at your disposal - then not renewing probably makes perfect sense for you. And the beauty is that you will still be able to use your current version to it's fullest without losing anything other than future updates.
