Can you hook up an Mac Mini or PC to an iMac display? The reason I ask this is..... I just purchased a Mac Mini and was thinking about buying an IPS 22-24" display as well as a new keyboard and mouse. The thing is once I do that it puts the Mac Mini at about the same price as an iMac. However, when the current version of the iMac becomes outdated and I want to upgrade to something else like maybe a more up date Mac Mini, or even a highend Mac will I be able to use this display, or will it have to be retired with the computer that is built into it? Thanks.
