Just bought a new iMac quad and I love it. I also received a replacement computer from Dell that is pretty high end. I use an HP 17 inch laptop as well. Set up Airport Extreme and everything seems to be working. Is there a way to use my iMac as a monitor for the Dell computer? I really love this monitor so much I hate to hook the Dell up to my Dell 24 inch monitor and would rather give up that monitor and gain desk space. The only other option is to use a Samsung 40 inch LED TV as my Dell's monitor. I use the iMac for video, pictures and music. I have Windows 7 running via Parallels but would rather just use the new Dell as a Windows computer and the iMac for personal use. This is my first experience with Apple and I really love it.
