If I have a 27" iMac, I understand I can use the display as an external monitor for my Macbook Pro. Presumably I can use the bluetooth keyboard as well as an external input?
Can you still run the iMac (and maybe instantly switch between them?). e.g. if I'm working on the Macbook using the iMac as a display, can I still listen to music on the iTunes library that's on my iMac, or switch to it to read a file (or download something from iTunes etc)?
