Everything Apple (the Mac heads thread)

If you mean you want to run your system on the imac and have access to the files on your laptop, just boot the laptop in target disk mode and connect to the imac via thunderbolt.

If you mean using the imac as an external display for the OS on the laptop, use target display mode on the imac.

If you want both systems running at the same time, you might (as mr_tom suggested) want to use synergy, using the LAN/airdrop/ to move files around.
