I am writing the following with the hope that someone at Parallels will read this and actually care:
I have used Parallels since v9. So far I have been very happy with my experience - until I downloaded the upgrade to v12. I use both MAC and PC to do my work. At the time I purchased my iMac, I maxed out the ram to 32GB - leaving my MAC experience with 16GB and my PC with 16GB - The recommended amount for the software I use on windows and MAC. Based on this, you can imagine my surprise and disappointment when I upgraded to the amazing new version only to find that, in true software developer fashion, you have changed the game without warning or concern. Limiting my VM to 8gb of ram because I refuse to purchase a subscription-based license for twice the price and an annual commitment (P.S. - I use my VM for hobbies and don't need a "PRO" version) is simply absurd. We all know that the glorious, resource-hogging windows OS can barely function on 8gb of ram - what's the point. This isn't 2005 anymore, we have no use for machines that can only, barely run a web browser and check email.
You have a product, it turns out that you found success because there was a need. You have now fallen into the trap of so many other developers and gotten greedy. Let me tell you something that you already know - nobody, NOBODY likes subscription licenses. Ever since the clowns at Adobe did it a few years back, every other developer with remotely useful software has decided that this should be the new standard. I have not upgraded and stopped purchasing adobe's CS since CS6 when they went to subscription. Subscriptions just give developers an excuse to release mediocre "upgrade" after mediocre upgrade since you don't actually have to fix anything or develop some new feature or tool that your users will want and therefore upgrade and boost your sales. As for parallels, I will NEVER purchase your software as a subscription. You have lost a loyal customer (one of may, I'm sure). I have always recommended your software to others who share my needs and interests, and there have been many. I will no longer suggest Parallels. I can't stand behind a company that unashamedly dupes their customers. Other options are out there, your organization would be wise to remember that in your pursuit of milking your loyal customers for more and more of our hard-earned money. I wish you were better than you are. Give us all a break.
