My display is currently hooked to a PC, but a lot of people at the office use Macs, so I recently bought a Mac to test some stuff that doesn't work quite the same. I didn't want a big box, or an expensive laptop, so I bought an old used mini.
I just wish they worked together. The mini is sitting hooked up to an old Dell LCD display turned sideways. The stand didn't turn sidewasy, so the display is just proped up against the wall on its side. Looks pretty kludged. Here's hoping that some day a Mac Mini can drive an Apple Cinema 30.
