Has anyone tried accessing a Parallels VM using Apple Remote Desktop or Windows Remote Desktop (for Mac) from a remote Mac. If so, how is the speed and performance? I use Windows Remote Desktop for Mac to connect to an XP box at work and performance is acceptable. I need to purchase a new computer in the near future and would like for it to be a Mac. But I have to be able to run Quickbooks (Windows) for various reasons. All of the OS X VNC clients I've tried are painfully slow and unacceptable for what I need. I am hoping that Apple Remote Desktop used with a Parallels VM is acceptable. Any thoughts?
