I'm a Mac. My wife is a PC... We are setting up a home office and we need to have the ability to run both OS X and Windows on my iMac. That's easy. The question I have is: can I link my iMac with my old iMac for multiscreen functionality, AND run Windows (through Parallels or similar) so that Windows also can be spread across both screens. I'm assuming the answer is yes, but would appreciate some recommendations as to the best method / software to get this done. TIA.
