I am a physician with an office inside the hospital. I upgraded my computer to an 27" 2011 Imac. I also want to upgrade my officemanager's office to an Imac. The problem is we still require a PC with windows. Easy solution for part of the problem is Paralells with windows running as VM. The hard part is that the program to access hospital records only available with a hospital computer on a windows pc. PWith the previous setup 1 pc for the hospital and 1 for the practice with a KVM switch so both pc's shared 1 moniter and 1 keyboard/mouse. I want a similar set up with the hospital PC and the Imac.I've been reading it is possible to use and imac as an external moniter for a pc, but not with the 2011 iMAc. So should I go look at a 2009 or 2010 imac with displayport, and vga adapter to display port, or get a mac mini with a 2010 27" moniter. Any opinions.
