From your website and from looking at the forums there seems to be several changes relating to the packaging and support offered by this year's set of Parallels releases. The changes that affect me at least include: Reduced memory limits per VM in the non-pro version. Snapshots moved to the Pro version. Vagrant support moved to the Pro version. Fine, I get that you feel that you should segment your market a bit and charge more for folks who might be developers, can't say that I like that, but I'd probably cope. But, you are also changing the Pro licensing model to an annual subscription, again, I don't like that, but it could be OK. Can someone from Parallels clarify exactly what you mean by "subscription"? From reading the forums, my understanding is that if the subscription lapses the software stops working? Please tell me that this isn't the case, I'm not in the habit of renting software and I've got no intention of starting now. When I read "subscription" I think of upgrades, fixes and support automatically for as long as the subscription runs, but that when the subscription lapses, the software continues to run but with no support. I'm fine with this. I've got very little problem with paying every year, I love the software and have been happy with the service, but I can also assure you that me and my employer have no intention of paying for time-bombed software. Finally, since you are adding a new subscription, there should be something on your site that explains the terms of the subscription prior to purchase.
