I can't say John that I'm altogether suprised at this response. Neither should you be. I warned you several weeks ago about how users (including myself) would not stand for paying for an upgrade to software which lacked advertised features, and were extremely buggy and broken. I realize that Parallels is a business, and they have to make money, but not at the cost of alienation of their userbase.
By the way, and this is not intended as an insult to you, but is English your second language? If it is, then it explains some of the posts I've seen.
Several of the posts you have up here are very fragmented, and hard to understand grammatically. I think if you're wanting to get your point across, you may want to reply to posters with a bit more clarity.
From what I've gathered, you've turned this thread over to management; so let's not torture John anymore and say directly to Parallels managment the following:
You promised features and functions in version 3 that did not materialize. You also released software that is known by the community at large and by Mac users in general (such as ArsTechnica for example) as being broken, unusuable by some and buggy to say the least. The predominant opinion on sites like ArsTechnica is that Fusion is a more solid and better product than Parallels. This is because of the problems with version 3.
Now you've released version 4, and expect people to pay for an upgrade from a piece of software that was broken to begin with. That's not good business. I've tested version 4, and so far, it's much better than it's predecessor. You've really put a lot of work into it. These are not people who are looking to get something for nothing; they're looking to get what they initially paid for. Version 4 needs to be free for all version 3 users. Provided version 4 stays as stable as I've seen it, then most users would be willing to pay for version 5 when you come up with it.
Do the right thing here.
