9 new versions in less than 8 years - would be great if you didn't have to pay an upgrade fee each time.

I'm settled on VMware Fusion. I did buy both in the early days of Intel Macs but stayed put on VMware Fusion after upgrading a few versions of each.

I can't say any of those features(!) promoted does much to make me want to move back to Parallels. I think I'll stay where I am.
