I've been quite happy with Fusion. - DeWitt Clinton

Fusion > Parallels for sure. Plus VMWare is much friendlier about upgrade policies -- at least they have been on Linux. I just switched to Fusion on the Mac because I was blown away that Parallels wanted to make me pay for a full upgrade to get a 10.5 compatible version. At least on Linux, VMWare always made "Make this work with new kernel 2.X.X" free. - Robert Cooper from twhirl

If I didn't already have Parallels, I'd do it! - MiniMage, sheeple of FF from NoiseRiver

I dumped Parallels for VMware and it works great. Parallels had an issue of not being able to share peripherals and the network with OS X. I haven't got VMware to recognize the built-in iSight camera on the iMac yet but read the procedures and it seems straight forward. - Larry Kless from twhirl

Oh, my Parallels won't work on Leopard? Guess I'll do it, then. Can it import my VM? - MiniMage, sheeple of FF

@MiniMage: If you have a version that isn't the latest, no it won't. And they will make you pay full price to get a version that will. I bought Parallels when the first shipped, and when faced with a forced upgrade, the extra $20 or whatever for VMWare is well worth it. VMWare won't run a parallels VM though. You can do a little dance and back up the old and restore into a new one, though. - Robert Cooper from twhirl

Dave, why don't you email me at pkazanjy [at] vmware d0t com - vmwarefusion

@vmwarefusion can i email you as well :) - Jay Martinez from twhirl

Also, @Robert Cooper: We have a handy dandy little tool called VMware Importer to import Parallels and Virtual PC for Mac VMs. No little dances required. Also, this is baked in to VMware Fusion 2 Beta 1 vmware.com/mac - vmwarefusion

I've switched to VMware from Parallels simply because for most of my work we share VM images between our engineering team, our customers, and partners. VMware is king in the commercial space. - Steve Giovannetti from twhirl

I use it to run the VMWare Linux images my company has pre-configured. - DGentry
