I originally purchased Parallels three years ago, but I have been using VMWare Fusion for just under a year. I use VMWare Fusion on a daily basis for my work and depend on it functioning correctly and performing well. My experiences:
1. Parallels was fair. The only major problem that I ever experienced was a one-time corruption of a VM. I'm not sure whether this was a persistent problem in Parallels, or I happen to get unlucky. In any event, it was not the reason I moved to Fusion.
2. Reason for moving: work. My work does much of its business using VMWare VMs: development, testing, demos, and production servers are all VMWare VMs running on ESX, Workstation, and Player versions. Having VMWare Fusion makes my life a lot easier in running and exchanging VMs with my colleagues and customers.
3. VMWare is rock-solid. I've not had a single crash (although I'm sure it has happen to someone) on the 30+ VMs that I deal with across a large variety of guest OS's: Windows XP, 2003, 2008, CentOS, OpenSolaris, Ubuntu, 32-bit and 64-bit OS's. We run enterprise databases on the them: Oracle 10g, 11g, and DB2 9.5. I've done Visual Studio development (in reviewing Silverlight technology for our product roadmap). I've run 4 VMs in parallel (on my Mac Pro) to simulate a multi-tier deployment of our application. It just works.
4. I don't play games in VMWare -- so no valid feedback on its graphic performance.
In sum, I honestly depend on VMWare Fusion to get my work done and it delivers. This is not a recommendation against Parallels, simply a recommendation for VMWare, based on my personal experience.
Good luck with your decision.
?I do have to question what's your motivation here - Do you have a vested interest in Parallels, or are you more concerned with telling me that I should behave more like you would? All you've done is get on an equally high soapbox, but this time for seemingly no reason?AppleMatt
While not an ideal solution, the fact that a manufacturer refunded money to an unhappy customer closes the issue in my book -- this is a relatively positive outcome.
