Is there a version 9 on the way or is it time to jump ship? I ask because Ubuntu and Elementary - my two favourite systems other than Mac - have become insufferably slow and I would love to keep them in working order in a virtual machine Rich::
I think you shouldn't be asking for a new version, you should be asking for an update to your current version that fix possible problems? I'm not sure you would want to pay for an upgrade for something that should be fixed in the current version?
I'm also unsure what's making your distros run slow... It might not necessarily be something that Parallels can fix. You should post a description in the appropriate Linux sub-forum.
