I have an iMac running Windows 7 on Parallels on OS X Lion. I'm going to be out of town and need access to my windows virtual machine. I have remote desktop working from my laptop to my iMac and connecting to my Parallels machine, however I am worried that if I lose power or lock-up, I will not be able to connect to my Windows running on Parallels. Because of this, I am thinking of purchasing Apple Remote Desktop. My concern is that it will be slow, like VNC. Windows Remote Desktop is extremely fast and efficient, but VNC seems to have very slow refresh. I am afraid that Apple Remote Desktop will be slow like VNC. Anyone who has used both version on Lion, could you give me some advice, and let me know your experiences with both. Thanks in advance.
