Main dev machine is an old MacPro, with 2 x 3GHz quad core xeons and 8 GB ram (and dual 30" cinema displays :) The laptop is an even older MacBookPro, first gen 1.83Ghz Core Duo, with 2GB ram. Still works like a champ. Windows 7 and Debian Squeeze run in vmware fusion VMs. Debian is also what runs on my deployment servers.
