I agree with the sentiment expressed here. I last used Parallels when it was at version 5, and have been using VMware Fusion since then--precisely because of the licensing issue. I, too, have two Macs--a MacBook and an iMac and switch between the two depending on whether I'm travelling/mobile or working from my home office. A few months ago I was all excited about the features in the latest version of Parallels, and installed a trial. Then when I looked at pricing, and discovered that I'd need *2* licenses, I uninstalled Parallels again and waited for VMware to update Fusion (which they did/do).
Not sure what Parallels is thinking--and I hope the model is working for you guys--but your pricing model leaves a bitter taste in my mouth. I cannot afford to pay more than double what Fusion costs simply to gain a tiny bit of extra "polish" over what Fusion provides. Just doesn't make sense.
If / when you folks reconsider (or, the oft-mentioned "management" gets around to looking seriously at this issue and makes a change for the better), I, for one, would be delighted--and would return to using Parallels.
